Denae Lacroix, an American working for MI5, is sent on a mission with only one other agent into Dreagan. She is confused about the secrecy of the whole deal, but follows her assignment. It isn't long before Denae is in a fight for her life and not from a hidden enemy but from her own people. She is about to be awakened to a world she never imagined and fall for the DARKEST FLAME burning.

Kellan, had slept for thousands of years. He awakes to watch as a man attacks a woman and since he doesn't care about humans at all he watches as the woman holds her own. He is tempted to let her die, but something makes him save her. He takes her to Con and the other Dragon Kings, planning to drop her off and leave. Something makes him stay and watch over her.

Denae has no choice but to tell Con and his people what had happened to her and they promise to help her escape the agency. Before she can escape and find peace the world around her explodes with more than just her betrayal leading her and Kellan into a fight for their lives, the other kings and their mates ... in fact the whole world.

DARKEST FLAME is a sizzling, high octane read. Author Donna Grant takes her readers back to Dreagan and her Dragon Kings with as fresh and thrilling a storyline as the previous books. Right from page one I was rooting for Denae and nearly applauded when she won the fight against her fellow agent. I also enjoyed watching as Kellan slowly lost his heart to the sexy, tough woman, who teaches him not all humans are bad. The sizzle was of course between the two of them when he finally gives in to his heart. There is also a bit of a side story that threads through this one concerning Con and a Fae named Rhiannon which adds a bit of drama and suspense. There is so much happening in this book you will be breathless by the end but ready to grab up the next Dragon Kings book as soon as it comes out. DARKEST FLAME is a real winner and a keeper.
