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.

A fantastic read in a fantastical world where Victorian London is entwined with Faerie treaties as part of the historic split from Rome and alliance with druidry. But it's still Victorian England — with its powerful few exploiting the downtrodden many, now with magically binding contracts. Enter Deri, a roguishly clever human assistant in the goblin market that lies beneath the city. It is an absolute joy to watch him barter and negotiate through a series of ever more treacherous high-stakes deals in an effort to secure his destiny, save his life, and free the sweet indentured workshop boy he loves. Everything has a price in this world. Will Deri give up his very heart's desire to achieve the destiny he's been chasing? 

Come buy! Come buy! And see what lies in this pealing tale where all's for sale and love comes dear
twixt hope and fear within the goblin market! 

(Get the audiobook for the 5-star experience. Narrator Will Watt is exceptional.)

Not enjoying it, not sure why. I usually love queer historical romantasy.
