A French village, new friends, fabulous food, a local mystery to be solved and . . . a ghost.

She snaps the locket shut. Just as quickly as he appeared, the boy is gone.

Josephine's heart is hammering. Her skin feels prickly and hot.

Surely, she's imagined him. That's the only possible explanation. Because boys don't live in lockets. Not unless they're ghosts. And ghosts aren't real. Or are they?

When almost-thirteen-year-old Josephine Eloise Thomas moves from Sydney to a chateau in the southwest of France, she expects many things - adventures, inspiration for the stories she loves to write and maybe finding out more about her French mother, who tragically died when she was a toddler. What she doesn't expect is to find a beautiful gold locket with the ghost of Louis XVII trapped inside!

After being accidentally released into the twenty-first century, the young prince proves to be annoying, strange and obviously from another time. He also believes that Josephine is not who she says she is.

Then, there's Gabriel. The grandson of the local baker - French, beautiful, an artist and definitely not a ghost.

When Josephine and Gabriel venture to the shadowy Chateau Du Lac next door to her home, the secrets become more sinister. With Louis's help, can Josephine and Gabriel discover what her neighbours are really up to and solve the mystery of Louis and the locket too?
