Penumbra — Kevin A. Davis

Will Haddie's power be enough? Haddie has a power she doesn't understand - the bizarre ability to move objects back in time - unfortunately not in one piece. With all that she has going on, Haddie ignores Liz's call. Later, when she listens to the message, the panic in Liz's voice is unmistakable, the words threatening to be her friend's last. Overcome with guilt, Haddie puts everything on the line to find Liz. Someone, or something disturbing is hiding amid the colorful lights and music of Portland's raves. Nothing could prepare Haddie for the supernatural creatures she uncovers in the search for Liz in the secret underground raves. Haddie races time to track down Liz before she becomes another victim. The next rave might be Haddie's last.
