"Brilliant."

"Rosen does humour very well, but this latest title from her is the best yet. It even had me laughing out loud, which is rare for me!"

"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."

"This is a stunning novella: cleverly-constructed, well-paced - and very informative. I read it in a single session and felt as if I'd been pulled through an emotional mangle."
