Some called her destiny a great privilege. She called it doomed to a cage with no key.Gatekeepers were born and raised to ensure time remained untainted and unchanged, but Brea saw them as overlords who looked down on her kind… on Seconds.

She plans to use her newfound status to help the plight of those born like her.But she never dreams of the twist her life will take, moving her into a higher position than she'd ever dreamed.

Will she and Jax always be at odds, or will their hearts bond together as their souls already have? Will Brea change the future of Lexcon, or will she be forever doomed to live life in the dark?
