Dragon Devotion by Emilia Hartley

If she knows the kind of person he is, she’ll dump him faster than an overloaded dragon can fall out of the sky.

Althea has time for everybody in the pack but herself. She’s too busy to sleep, but not busy enough to distract herself from her aching loneliness. When she finds a dragon shifter caught in a bear trap, that loneliness (or maybe that lack of sleep) prompts her to propose a fake marriage to help him find needed sanctuary. Griffin is thoughtful, charming, and oh-so-sexy. He also appears to be into Althea. His jokes mask a deep darkness, though, and Althea has to remind herself that their relationship is all a sham.
Griffin has come to upstate New York to locate the last two of his father’s offspring—Alistair and Devin VanTassel. What he finds, though, is not just the two dragons he expected, but a growing family that includes children—and a whole pack that depends on the cousins. He also finds Althea, the hardest-working, sweetest woman he has ever encountered. He’s drawn to her, but she’s too good for him, too good even for the pack she works tirelessly to mother. All he knows is he can’t turn her or her pack over to his bloodthirsty sire, but he doesn’t know how to keep the monster away from them without sacrificing himself. Maybe that will be a fitting end for his sorry, cowardly life. Traitors like him certainly don’t deserve the kind of bond that seems to e growing between him and Althea.
