Bo attempts an unlikely rescue against an army to save two people who are dear to her – unaware of the dangers facing those she leaves behind. Kenzi has an epiphany about Hale. Dyson is given an important clue to Bo’s past, just as doubt is cast on his own future.

With Hale otherwise incapacitated, Tamsin saunters in to fill the void as Dyson’s partner on the force in the human world. But there’s a catch – she’s Dark Fae. Part of a program to strengthen relations between both Fae clans in the wake of the Garuda’s assault, Tamsin is cool, kickass, and more skeptical than most when it comes to everyone’s favorite Succubus. Tamsin is here to make nice and play by the rules, but her loyalty and trust is not so easily won over. She’s a Valkyrie, a clandestine breed with some serious cred in the Fae world, with an agenda that’s higher than even the Morrigan’s pay grade. And though her powers are as mysterious as her past, there’s no doubt that you’d want Tamsin by your side in a bar-brawl. Who knows, Tamsin might just give Bo a the taste of the Dark that finally tips her over the edge.
