Written by Polly Horvath in 1999, The Trolls is a child's novel based in the present time with stories told by Aunt Sally dating back twenty or so years ago. The Trolls was a National Book Award finalist, and is a Boston Globe-Horn Book Award Honor book.

The books starts out with Mr. and Mrs. Anderson, parents of Melissa, Amanda and Pee Wee, having planned a trip to Paris, but the babysitter cancels last minute due to a development of bubonic plague requiring them to resort to the only available person left: Aunt Sally. Once Aunt Sally arrives and the children’s parents leave they are treated to many of Aunt Sally’s stories revolving around her life in Vancouver with her eccentric family.
