Great review for Warrior Stone
C Horner (thank you C) says 'Stone Rocks', and adds:
“Warrior Stone : Underland” is reminiscent of Neverwhere, and if you liked that you’re likely to enjoy this. Harkess has put a lot of thought into the world he’s created, with the different races; the bureaucratic, cunning Grenlix, the Hrund who provide the muscle, the dangerous, scarcely-seen Angels, who are in no way angelic. He has also done a very good job of getting inside the head of an awkward teenage girl – Claire might be flitting between the Real and Underland, but the problems she encounters in both realms will be familiar to all, from school bullying to embarrassing encounters with attractive boys."
