Hilda and the Troll (#1) by Luke Pearson (6+)

Meet Hilda. She can never sit still for long without setting off on another adventure.  Join her in discovering a magical new universe!

While on an expedition to seek out the magical creatures of the mountains around her home, Hilda spots a mountain troll. As she draws it the blue-haired explorer starts to nod off… when she wakes, she finds herself lost in a snowstorm and her troll has totally disappeared. On her way home, Hilda ventures deep into the woods, befriends a lonely wooden man and narrowly avoids getting squashed by a lost giant.
