Witch’s Moon by Nina Croft

A witch and a werewolf—a match made in hell.
Regan is about to play a leading role in someone’s plans for world domination. And all they need to do to ensure her cooperation is bite her.
Regan doesn’t do scared. It’s not who she is. But right now, she’s panicking. Being a werewolf is dangerous and one wrong step could mean the End of Days. And the only person who can help is the stunningly gorgeous, embittered son of the werewolf who bit her.
Caleb Stone wants an ordinary life. After a horrendous childhood, he fled the pack and now does a pretty good job of pretending he’s human. Self-delusion at its best. The last woman he wants to get involved with is a witch turned werewolf. However explosive the chemistry between them.
But soon it becomes clear that Regan and Caleb need each other, and together they’re going to uncover secrets that will turn both their lives to chaos.
