Girl Three: Trapped — Molly Black

In GIRL THREE: TRAPPED (book #3), case three has just landed, and the clock is ticking. The suspect, a copycat of the Moonlight Killer, seems to be using sophisticated audio equipment to stay one step ahead of his victims -- and Maya herself could be next.

Maya, knowing the killer has her sister, has no choice but to accept the case. More determined than ever, she revisits the prison where the last convict hung himself in hopes of uncovering a new lead. But with the murderer able to track her every movement, Maya realizes that she's the least safe of all.

And in the midst of it all, a bunny escapes.
