More Than Truth (The Arcane Book 3)

Two halves of a whole, rare Drachon twins Taggart and Vincent Jennings once shared the weight of being the salvation of their people until Vincent disappears, leaving Tag to bear their people's disappointment alone. Now Vincent is back, demanding Tag help him rescue the one woman neither can live without, but they're going to have to repair their own relationship if they have any hope of convincing her to take a chance on them.
Years ago Dr. Brit Mahoney helped develop genetic research that had the potential to enslave the entire Arcane to the Triumvirate and she sacrificed everything she loved to destroy it. Determined to never allow her emotions to make her vulnerable again, she's buried herself in science, refusing to allow herself to succumb to her desire for Taggart Jennings. Then his estranged twin appears and their combined hormones ignites a mating heat that is even more than she can withstand.
When it becomes obvious Brit's research was resurrected with fatal consequences, Vincent must reveal the horrible truths of his past to give them any hope of a future.
