Anastasia, Ollie and Quentin have barely managed to escape the nefarious clutches of C.R.U.D. when they are brought to the underground Cavelands. There Anastasia finds out she is Caveland royalty, and that her family figures into a centuries old scandal that began with the disappearance of her grandfather.

"A wild, nameless girl the townspeople call Wee Sister Strange roams through forests and marshes and bogs in search of a bedtime story"--

Anastasia, nearly eleven, is snatched from her elementary school and sent to live at a former insane asylum with two great aunts she had never met after being told that her parents died in a tragic vacuum cleaner accident.
