The Royal Society for the Prevention of Cruelty to Beasts (RSPCB) operates a rescue center for werewolves, dragons, fairies, giants, sea monsters, and other fantastical creatures. The RSPCB has stopped crimes against beasts, but some people still seek these animals, even if it means crossing the society’s members. In this book, a dragons mangled body arrives at the RSPCB, indicating a real monster on the loose. Ulf, a werewolf-boy, and his friends must stop the evil beast hunter before it’s too late. The adventure continues in the second book, Sea Monsters and Other Delicacies, where Ulf and his friends face new challenges involving a sea monster and the return of the villain Baron Marackai.
