This special treasury edition contains the first two volumes of Hilda's adventures -- Hilda and the Troll and Hilda and the Midnight Giant -- for you to read over and over again, as well as bonus material from series creator, Luke Pearson.

"We rejoin our heroine for her latest adventure just as she awakes to find herself ... in the body of a troll! Her mother 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!"--Provided by publisher.
