It's really smart. It's fantasy, what Daniel referes to as "High Fantasy." In other words, its on the intelligent and literate side of fantasy, versus the formuliac stuff churned out for adolescent boys. It has romance, grimly realistic politics, and characters that come alive off the page. It's very human, there's a lot of ambiguity, its genuinely on of the best new books I've read for awhile. Especially if you like fantasy, you should give it a try.
You don't have to just take Jae and I's word for it. He's getting some rave blurbs from big league writers, such as Connie Willis.
"Reader, be warned: If you open Daniel Abraham's A Shadow in Summer, he will lead you into a strange, seductive world of beatings and poets and betrayals, intrigues you do not fully understand and wars you cannot stop and places you are not sure you want to go. Intricate, elegant, and almost hypnotically told, this tale of gods held captive will hold you captive, too."
--Connie Willis, Hugo Award-winning author of To Say Nothing of the Dog
The book is _A Shadow In Summer_, by Daniel Abraham.
