What do the three members of a popular boy band, twelve teenage “Dairy Princesses,” a family of hungry trolls, a cunning fox, and a magic fiddle have in common? They’re all elements in Troll Bridge, the second in Yolen and Stemple’s “Rock ‘N’ Roll Fairy Tale series, which draws upon several different fairy tales to create something new and magical. In this fast-paced tale, it falls upon two unlikely heroes – one a harpist, the other a rock musician – to outwit their ancient captors and unweave the manipulations of a dubious ally in order to save the day. As an added bonus, this book contains original lyrics by musician Adam Stemple (formerly of popular groups Cats Laughing and Boiled in Lead). Overall, an intriguing read but over far too quickly.
