Almost halfway through Shinbone Shadowhunter, its Ok but no comparison to Terry's stories.
Then again, looking at the genre: of course not. It's a "medieval cosy mystery with comic fantasy humour" (Amazon). Whoever wrote that sounds like he didn't know which genre this book is supposed to be.
Whoever compared that to Terry in the SFRevu is barmy. Apples and oranges, mate.
It's also worth noting that this is a novella, so it would be slimmer by necessity. A comparison to "Eric" might be appropriate.
