"We fight together. Always."

When she is attacked by a biological weapon, demon hunter Alexandra Kingston doesn't suspect her Protector and childhood friend of betraying her. But when Flyn hightails it out of town with more money in his bank account than an operative makes in a lifetime, she has more questions than answers. Given orders to get Flyn's source of information or else, Alex believes only the truth will save her sexy bodyguard's life.

He would decide who he sought dark secrets for.

Alexandra can never be his. She is the preordained future leader of Blades, and he is a lowly operative assigned the position of her Protector. But Seeker Flyn Severins will do anything to protect her, even be branded a traitor for refusing to give up the dark secrets in his mind—truths that threaten to destroy Alex's family.

As secrets are revealed, and bloodlines and loyalties are questioned, will Flyn and Alex defy Fate and their laws of power and position for a chance to be together? Or will Alex choose duty over love?
