Incarceron (Incarceron, Book 1)

Amazon Best Books of the Month, February 2010: The shifting landscapes, unexpected plot punches, and bold, brave characters found in Catherine Fisher's Incarceron are nothing short of thrilling: fans of Garth Nix and Suzanne Collins will take to this epic, twisty fantasy instantly, but it's also the kind of book that will draw in the most hesitant fantasy reader. The mysterious world of Incarceron and its factions of daring Prisoners, led by an incorrigible team in Finn and Claudia, who are both searching for a means of escape is wonderfully imagined, at once frightening and full of seduction, and marks the beginning of an addictive new series. --Anne Bartholomew
