In ‘The Book of Revenge,’ the final book in E.R. Murray’s Nine Lives trilogy, Ebony Smart faces her toughest challenge so far. Her enemies, Judge Ambrose and Zach Stone, have a powerful new ally and an army of Shadow Walkers to use against her. Without the help of The Book of Learning, Ebony, with pet rat, Winston, and the Order of the Nine Lives, must find a way to discover their plans, defeat the magical beings and rescue her parents. A story of ghosts, time-travel, battles and dark magic, this is Ebony s greatest adventure so far but will it also be her last?
