This book is clever as you need to be to make a profit trading with a goblin. I loved the growing relationship between Owain and Deri, and while it's a bit horny, the writing is very tasteful about it. The conceit of paralleling indentured servitude Above with Untermarkt trades and contracts is excellent. This is a dark book full of exploitation and risks that make it a more stressful book than a comfort read to me. Certainly not a book I'd trade away my memory of to read again for the first time, but I won't write off a re-read having value.
