Killer Dreams - Vincent Donovan - Bog

Are the voices in Cassie's head real or just added mayhem?
Cassie MacLean has been under siege since that cold January night when her mother, Rose Owens plowed into a group of pedestrians killing five and critically-injuring many others. The town's pent-up fury explodes when Rose begins to emerge from a coma ten years later.
Cassie feels conflicted about the awakening-as well as her father, who is enjoying a successful second act with another woman.
But after a brush with cutting-edge technology, Cassie believes her mother is innocent and embarks on a quest to prove it. While she risks alienating many and having her sanity questioned in the process, what's not in doubt is a vengeful world where the truth depends on who you ask.
