Dragon Kisses — Michele Zurlo

Waking up in a strange barn was just the tip of the iceberg. Cassie and Niall find themselves transported to another world, one full of dragon shifters who want to possess them. Cassie is claimed by Illion, an electric blue dragon who shifts into five hulking men, and Niall is claimed by Wynn, a lime green dragon who shifts into two men and two women.

The Zmaj feed from the sexual energy of humans, and finding a cache of five in an abandoned barn is a momentous occasion. Convincing them to stay and protecting them from the Inamanida, their sworn enemy, is another task altogether. And falling in love? Zmaj don't do that.

When Cassie runs away, Illion is forced to confront his prejudices and his brethren in order to save her from a fate worse than death.
