"Brilliant."

"This is another page turner from Rosen. The characterization is spot on, the pace is perfect and she is the mistress of suspense."

"You can tell that Ms Trevithick was a fan of Roald Dahl when she was growing up. The stinky trolls in this story are reminiscent of the giants in The BFG and, if possible, even more revolting. Her strong authorial voice and witty prose will appeal to parents as much as children; I caught myself chortling out loud at least every other page."

"An absolute corker of a read."
