Demon Doppelgangers (Charmed, #32)

Paige has a new job — and it's perfect for her. She's working at a museum, conducting tours through a traveling Grecian display. It's temporary, but it's better than nothing, and it means she gets to see Chase, a really hot guy who started working at the museum at about the same time she did. One day, though, a big stone ovoid meant to represent a dragon's egg turns up, and it gives her the creeps. When Paige asks Phoebe and Piper to come check it out, they agree there's definitely something evil about that weird old egg.

Later, after a long day of tours, Paige and Chase relax near the artifact. Without warning, Chase, who knows only a few Greek words, begins speaking in the language. His monologue opens the egg, releasing a demon that promptly assumes Chase's form. When Paige tries to kill it, it splits in half, forming two identical Chases. With the real Chase unable to explain what happened and demons on the loose, the Charmed Ones will have to count on the Power of Three to figure out what's doubling these demons...and why.
