Flicker

Biz is a perfectly normal teenager except for one minor detail: she uses sunlight to jump back to yesterday. She takes advantage of flickering by retaking Trig tests, fixing fights with her boyfriend (or reliving the making up), and repeating pretty much anything that could be done better.

Trouble is, flickering makes her head explode from the inside. Or feel like it anyway.

No one knows about her freakish ability and she's content to keep it that way. Guys don't stick around because she refuses to let them in, but all that changes when Cameron, her best friend, starts looking oh-so-yummy. Suddenly she's noticing his biceps, his smile, and the cute way his eyes crinkle when he — gah! This is her friend!

But the butterflies come to a screeching halt when little girls start disappearing, then take a nosedive when the police link the kidnappings to Cameron's sister, who vanished years earlier. As the police grasp for clues, Biz photographs a strange man lurking in the shadows and realizes that her flickering can help more than just herself.
