Quinn comes through the portal into this world on a mission: make sure it's a safe haven for her best friend, the pregnant wife of her world's leader. But she no more than gets here when she's confronted by the ghost of Caleb Marshall, a werewolf who was killed there 75 years ago. She and Caleb are drawn to one another, but what's the future in falling in love with a ghost? A ghost who's stayed around all these years to avenge his death on the descendants of Aden Marshall, his cousin, the man who killed him.

Then Caleb takes over the body of a murder victim. That solves the ghost problem, but he's still hell-bent on revenge. That's only one of the problems they face, because they discover the man whose body Caleb has entered was murdered by a paramilitary group that plans to set off a dirty bomb. Quinn is falling for Caleb, but he has to let the revenge thing go. And if they want anybody near Washington, DC to have a future at all, they must stop the militia group.

GHOST MOON is a great addition to Ms. York's Moon series. The Marshalls are there in force, working together in spite of their Alpha natures. Quinn is a good match for a Marshall werewolf, and several of the Marshalls and their mates show up to help them save the day. Good plot, great characters and a major woo-woo factor combine to make this one a very good read. Don't miss any of the Moon series -- they are a real treat.
