Dare (A Greystone Novel #2)
The victim of a harpy attack at seventeen, Dare lost his wings and his poisonous barbs. When he meets Mim, he doesn't consider himself much of a catch. But Mim is the only power that can make the broken gargoyle whole again. And when she's abducted by a harpy, he's willing to sacrifice himself for her freedom.
Which might have worked, if Mim hadn't been willing to do the same thing.
