Her tortured secrets drove her into the arms of his rival, but desperation has brought her back. As a horrifying new weapon of mass destruction is about to be unleashed, Tiberius and Caris harness the power of their immortal and passionate love. But will it be enough to battle devastating odds and a ruthless enemy with the ambition to destroy them all? Don't miss J. K. Beck's short story "Shadow Keepers: Midnight" in the back of the book.
