See what perils await this beloved blue-haired adventurer in the sixth book of Luke Pearson's widely praised series.

We rejoin our heroine for her latest adventure just as she awakes to find herself...in the body of a troll! Her mum is worried sick, and is perplexed by the strange creature that seems to have taken Hilda's place. Now, both of them are in a race to be reunited before Ahlberg and his safety patrol get the chance to use their new secret weapon to lay waste to the trolls, and Hilda along with them!
