Myra and Kassy Cooper have discovered a magic library. An evil witch is taking characters out of the books and making them forget who they are.
Myra and Kassy have to save the characters before their stories disappear forever.
A very smelly book leads Myra and Kassy to a troll who guards a bridge. The troll doesn't think he needs the girls' help, until his appearance starts to change.
Panic soon sets in amongst the troll community as the evil witch's magic works on them.
Myra and Kassy have to help the trolls before it's too late – but at what cost?
