The Shifter’s Soul by R. A. Boyd

Simon Nichols would rather give up his soul than go on a murderous rampage and be put to sleep for the next century. He gave up the most vulnerable part of himself to keep his clan safe, but now all he can feel is pain. He invites it. He craves it. But when he meets the curvy, silver-haired beauty who keeps threatening to break one of his vital body parts, he can’t help but want to feel more of everything she wants to offer.
Charlie Hinders can’t stop thinking of the rude, sexy, yeti of a man who keeps popping up to keep her from tripping over her own feet. Air and gravity are not her friends. She doesn’t want anyone asking about the life she left behind but that’s all Simon seems to be interested in.
Throw in a ghost in Simon’s house, sisters who intrude way more than is healthy, and a new threat to the Ghost Shifters that could snuff them out of existence for good… it’s going to be a busy week.
