Libby lives with her mean step-brother, Rex, who tells her scary stories so she can’t sleep. At school she is a loner. All Libby wants is a best friend – and to get revenge on Rex.
Libby’s life changes forever when she finds, in an old trunk in her bedroom, a little purple wolf-like creature named Wulfie.
Wulfie can talk. He can grow as big as a bear or shrink down as small as a snail. He’s sweet and kind, but he loves to get into trouble.
