37688226The Thorn Queen by Elise Holland was a fairly standard middle-grade GU adventure fantasy story. I have to say I almost gave up on it at first because it just felt like it was throwing a lot of “clever” world building at us all at once (so many new words for seemingly random invented creatures!) but I stuck with it due to the GU angle and it ended up being relatively enjoyable from that perspective, especially with a nice twist as to the identity of the Adversary (although for once, I did see it coming).

Meylyne, 12, a resident of the Between-World, foolishly trespasses into the forbidden Above-World, ignores a warning, and gets herself and her family into some serious trouble. The only solution, upon the advice of a wise well, is to embark on a quest ostensibly to heal a sick prince, but ultimately to save her entire world. She acquires an animal companion, and then a human boy after she rescues him. They discover that a figure known only as the Thorn Queen has been causing mayhem and weakening the entire land. When she finally uncovers the Adversary, it comes with a revelation about her own true nature – as well as the customary attempt at temptation. She then journeys underground to the Beneath-World where more is revealed about her history and powers. With time running out, she must heal a friend and save the world, after a final confrontation with the Thorn Queen.
