Elena and Raphael return for the hauntingly poignant conclusion to New York Times bestselling author Nalini Singh’s genre-defining Guild Hunter series.
A thousand years.
It’s been a millennium since Elena’s fateful first meeting with Archangel Raphael. She has survived war and loss, experienced beauty and cruelty. But no matter what, she has always held on to her mortal heart, as she and Raphael have held on to each other. Passionate and vibrant, they’ve built a life that has stood the test of time, growing ever stronger with each turn of the sun.
But change is coming—of a magnitude they could have never imagined—and it will forever alter the trajectory of their existence.
Even as they grapple with the cataclysmic shift in their personal lives, the Cadre of Ten, which has maintained a hard-won peace for centuries, begins to simmer with dangerous fault lines. The specter of madness looms in one archangel, the promise of war burns between two others, and in darkness far from mortal and immortal eyes stirs an ancient, slumbering power.
Suddenly, the future is terrifyingly uncertain . . . at the very moment that Elena and her archangel need to protect a treasure infinitely more precious than eternity.

Oh, the sadness of saying goodbye to this beloved series. Thank you, Nalini Singh, for giving us the perfect farewell.

As we have all been waiting for all these years, our favorite Archangel and his Hunter/Angel Made consort are finally going to have a super-parasite a/k/a a baby. It was nice to see that two millennia-old beings were plagued with fears and concerns about becoming parents just like the rest of us.  Elena hasn’t had nightmares about her mother and sisters for centuries but since she has become pregnant, her thoughts keep going back to her worst fear.  Same with Raphael, his concern goes back to both is parents succumbing to madness.  First his mother had to kill his crazed father and then she eventually left a young Raphael broken and bloody in a field. His concern is what if he too goes mad like his parents, who would be able to protect his child from a mad archangel?

While Elena and Raphael fret about what kind of parents they will be, the story bops around between the past and the future where Elena reminisces about the mortals in her life who are gone, especially her mother and her best friend, Sarah. We also spend time visiting those millennia-long friendships she has developed with vampire and angels over the course of the series. It becomes a nice blend of memories of old friends and those currently most important to Elena and Raphael. We also have some characters who will leave us and some who return for one last bow before the end.

The story isn’t all kittens and rainbows and catching up with old friends. There are some tension-filled issues to be dealt with as well. The baby is showing mortal cells in their blood test so will the baby be mortal or immortal? Things between Illium and his father are becoming unbearable with his father threatening a war between the two. Will war break out?  While everyone will certainly step in and back Illium, they can’t step in until Aegaeon makes a move and as a much older archangel, he could do serious damage or even kill Illium before Raphael and the Cadre step in. And while Elena and Raphael are celebrating their bundle of joy, we also have the downside of immortality.   Elena’s brother-in-law has  shown up–remember Beth’s husband who changed to vampire before he knew Beth was incompatible–Harrison is now as old as Elena but he is succumbing to depression. He has been alive for centuries but no longer feels any desire to go on. His wife is long-dead as are his children and he no longer feels any connection to their descendants. Immortality seems like a great idea but days get longer and longer when there is nothing to look forward to. There aren’t many ways for a suicidal vampire to die at his age and he seeks out Elena’s help. Elena promised her sister to watch out for Harrison so she is doing everything she can think of to save him.

I also really liked that we also have the child being born about two-thirds into the story which allows us to spend a nice portion of this final story seeing how their baby grows into an adult and how Elena and Raphael take to parenting and how their extended family supports their family unit.

With 77 chapter, I had hoped this story would never end but too many of them told their part with only a few pages, and in the end, the end came way too soon. I did appreciate how each Chapter started with a quote from the various novels of the series, most of which I remembered.

This was our final time with our beloved characters and this story was definitely a love letter to the fans taking us back through the past and into an amazing future with our favorite couple as they become the perfect little family.

Favorite Scene:

SCENE EDITED — YOU HAVE TO WAIT TO FIND OUT THE BABY’S SEX AND NAME FOR YOURSELF.

Three weeks out from the birth, and Elena was sitting in a swinging rattan chair lined with plush cushions on one of the stronghold’s balconies, (Baby) in her arms and the area heated by the clay pots, when she glimpsed wings of distinctive blue against a cloud-gray sky.

She was certain she was hallucinating–because surely, with border tensions continuing to simmer, Illium would stay close to his territory.

The blue came more and more into focus.

Until there was no denying it. “Raphael! Illium is here!”

Her archangel, who’d been working inside the study just behind her, stepped out onto the balcony. “Of course he is,” he said in a wry tone.

Illium landed on the balcony with all the dazzling lightness of which he was capable.

A small blue feather floated up into the air, a dancer as light as their Bluebell.

“Would you believe I was in the neighborhood?” he said, his hair wild and his breath uneven–which indicated exactly how fast and hard he’d flown.

Archangels don’t easily lose their breath.

Wanting only to hug him, she said, “You’re a lunatic.”

He grinned, unabashed, as he greeted Raphael the way the two always did when alone–with the forearm clasp of warriors that ended in a back-slapping hug. “Hello, fellow archangel who is not my sire,” Illium said, as cheeky as always. “I’ve come to visit my (family relation).”

“(Family relation)?” Raphael raised an eyebrow, “How do you figure that?”

“Well, I am definitely going to be Uncle Illium, so they must be my (family relation).” He was by Elena’s chair now, his eyes on a wide-awake (Baby), who she’d wrapped in a soft blanket gifted by Honor and Dmitri.

Smiling so hard that her face might crack, Elena lifted the baby toward Illium, knowing that Raphael–hyper-protective mode or not–would never worry while their (baby) was with their Bluebell. “Here,” she said. “You can hold (him/her).”

But Illium looked to Raphael first. Who gave a small nod.

“Wait.” Illium stripped off his leather jerkin to expose a sleeveless undershirt of soft, well-worn cotton.

Then, taking (Baby) in careful arms, he cradled (him/her) to his chest as baby and Bluebell stared into each other’s eyes.

Elena’s heart swelled.

“Can you say ‘Uncle Illium’?” A deep murmur. “I’ll even accept ‘Uncle Blue.’ ‘Illium’ is a bit of a mouthful.”

“How did you get away?” Raphael put one hand on top of the swing chair. “Is Aodhan holding the territory?”

Illium made a funny face at the baby. “I flew out under cover of darkness using glamour. The dickhead doesn’t sit at the border, just has his troops there, and he’s the only one who would’ve been able to see through that, so my territory’s safe against a surprise attack. I’ll be back before he even knows I’m gone.” He nuzzled (baby). “Uncle Blue, (Baby Nickname),” he whispered.

Elena looked up at Raphael. Trust Bluebell to call (baby nickname). It had thus far been her and Raphael’s private pet name for their baby, but it seemed right that Illium should instinctively use it. He’s never going to change.

He did threaten just that when he first became Cadre Raphael had worried for the man he’d watched grow from the time he was a tiny blue-winged boy boisterous and loving; he hadn’t known how Illium would survive the lethal politics of the Cadre, not when his heart was so wide open.

But Illium had been a first general. He knew how to lead–and how to deal with predators. It just so happened that he also led with humor and such good nature that his people adored him.

As did Raphael’s Elena.

He’d worried that he’d feel as dangerous toward Illium as he did even toward Elijah right now, but that had turned out to be a needless fear. Because the primal core of him remembered he’d once held a blue-winged boy’s hand, that he’d cradled a crying toddler against his chest, that he’d put a wooden practice sword in the hand of the child who would grow up into this archangel.

Then later, when it was time, he’d given the same child his first true sword.

Theirs was a relationship unlike that of any other in the Cadre, until when they were alone, Illium still deferred to him.

As Raphael did to Lady Sharine, even though she was no archangel.

Certain things were beyond angelic law or tradition.

“I’ll get some food up here.” He was conscious that Illium had to have burned an incredible amount of energy with the intense speed of his flight. “When do you have to leave?”

“Within the hour. Can’t risk anything more with the dickhead massing his troops.”

Much as Raphael wanted to ask him about that situation, he decided to leave it for a later call. Today, this visit, it was about joy–and about their child meeting Uncle Illium for the first time.

Who held (Baby) for the entirety of his visit, with their child quite content in his strong arms. “I’m going to give you your first practice sword,” Illium declared, then shared a glance with Raphael, his wide-open heart right there for all the world to see. “If your papa will allow it.”

Had anyone asked Raphael yesterday, he’d have said that of course he would be the one to give his child their first practice sword, but today, his chest expanded with the knowledge that this was right, was how it should be. “Yes,” he said, his voice rough. “It is tradition now, I think.”

Eyes shining, Illium looked down at (Baby). “Your uncle Aodhan is already fighting with your honorary extra grandmother about which one of them will do your childhood portraits.”

His grin creased his cheeks. “I think they have come to a détente–to take it in turns.” Lowering his voice to a whisper, he added, “I don’t trust either of them. Mark my words, they’ll be sneaking sketches whenever you’re around.”

I helped raise this man, Elena, Raphael said into his consort’s mind, his hand clenching atop her chair as his eyes burned. And he is extraordinary.

Elena lifted her head. Yes you did, and yes he is. Her smile filled his world. You’ll be an amazing father to (Baby), Raphael. The proof is sitting right in front of you.

Raphael took a jagged breath of the cold, clean air.
