The Keepers [Herron]

Still haunted by his wife's murder - and stained by the blood of avenging it - FBI special agent Hatcher McGee can't believe he's being teamed up with rookie agent Korine Davenport. She is his most guilty secret - the one-night stand who almost cost him everything. Korine has her own demons. As a child, she witnessed her father's murder, and she's spent her life waiting for the killer's return. She and Hatcher are both looking for closure, but the disturbing case that draws them together could be their last.

Tinsley Jensen survived the torturous clutches of an elusive masked killer dubbed the Skull, only to be held hostage by her nightmares. She’s terrified of leaving her cottage on Seahawk Island, knowing that the madman is still out there. FBI special agent Wyatt Camden knows it too. He may have rescued Tinsley, but her captor got away. Now he’s driven by guilt, the need for vengeance, and the desire to protect - at any cost - the woman he’s come to love.
