House of Hollow by Krystal Sutherland is a young adult novel that really grabbed my interest as soon as I started to read. It revolves around three sisters that mysteriously disappeared when young and later returned. However, they were changed and kept changing into beautiful girls with black eyes, white hair and huge appetites that never affected them. When one of them disappears, it is up to the remaining two to find her and solve what really happened to them so long ago.
