Dead to You by Lisa McMann

This is the story of every family's worst nightmare... a seven year old son, abducted from his own front yard. Years spent searching, always hoping, never believing the worst.

This is the story of what happens when that little boy returns home nine years later. When he doesn't remember the house, his family, his best friend. When he feels the need to protect his abductor Ellen/Eleanor, even though she later abandoned him. When his little brother doesn't believe it's really him.

This is the story of Ethan De Wilde.
