Glass shatters

"A man wakes up in a living room he doesn't recognize, unable to remember anything about himself. All he has are the few remnants of his identity scattered throughout the house--clues to his past. He soon learns that he is Charles Lang, a brilliant scientist whose wife, Julie, and daughter, Jess, mysteriously disappeared several years ago. Soon, he begins to recover memories--memories that may or may not be his own--and as he does, he realizes that only by uncovering the details of his former life will he have any hope of reuniting with Julie and Jess."-- taken from back cover.
