Choosing the Dragon by Rinelle Grey

As if her ex-husband showing up out of the blue wasn’t traumatic enough for Rylee, the jerk knows about Calrian, and he told her father. Now her dad wants her out, and Rylee has nowhere else to go. She and her son could soon be homeless, if Rylee can’t find them a new home.
Calrian wishes he could help her, but aside from offering her his support, there’s nothing he can do. He might be a dragon shifter prince, but he knows little about the human world. The best thing he can do is find his clan, then maybe he’d have a home to offer Rylee.
With no one to rely on but each other, Rylee and Calrian must work together, or risk losing everything.
