A Companion to Wolves by Elizabeth Bear and Sarah Monette.
It had sat in my To Read pile forever, because I knew it was "problematic" (oh how I hate that word). Now I feel stupid for having listened to that and read other things before it.
It's sort of like a mix of Dragonriders of Pern and that old Elfquest comic from the 80s:
(Boy is it hard to find not-awful Elfquest artwork!)
I haven't read the Pern books in decades, so I'm not sure how closely A Companion is to that world, but the basics seem the same. A wolf chooses a person to bond with, and a mental connection forms between the two. They live and fight together, with a group of other bonded men.
Unlike Pern, all the people who bond with wolves are men. Like Pern, there's a bleeding over of reactions during breeding times (female wolves going into heat). Related to that: I've never seen such detailed male/male sex in a published, non-erotic book before!
It's killing me to not be able to read others' reviews, thoughts on it, details about the next books. I want to dive in and read EVERYTHING online about it... but I don't want to get spoiled.
...okay, maybe this is turning into a book review. I better end this post now, or I'll have nothing left to say once I finish it and write the official review! :P
