The other side of dark by Joan Lowery Nixon

 "Stacy wakes up in a hospital room, in a body she doesn't recognize."
This suspenseful and mysterious book talks about a seventeen year old girl, Stacy, who still thinks she is a thirteen year old and only has as much knowledge as that. She surprisingly recovered from a gunshot wound, only waking up to realize that her mother was murdered. She remembers the killer's name, but has a shadowy memory of his face. Her best friend, Jan, helps Stacy try to regain back her memory, though Stacy feels like she's alone.. Everyone matured, and she still feels like she's thirteen.. Will she regain back her memory before the killer discovers she had recovered and decides to get rid of her again?
I would rate this book a 7/10 because I expected more suspense and mystery to the plot .. though it didn't really happen. I would still recommend people who likes suspense and mystery, but does not want to get scared too much, to read this ! :)
