A lion shifter.
In a clan of shifters, the lions are considered most powerful and respected. Jace is headstrong, willful, has fun with women but doesn't see the big rush to find a mate. His father lays it on the line: If he's to head the clan one day, he needs to find his bride. He resents being told what to do.
A desperate hottie.
Gemma's got her own set of problems, and saving Jace from a group that collects shifters for sport and research shouldn't be one of those problems. So what made it her problem?
A mutual problem and raging hormones.
