Gilda Joyce is Nancy Drew for a new generation - and she's back in her spookiest mystery yet!

When Gilda Joyce's mother gets engaged to a man from St. Augustine, Florida, Gilda is appalled. She hasn't even given him the "Joyce Family Application" yet! But as the wedding preparations get under way, Gilda realizes the application is the least of her worries. Spooky St. Augustine is riddled with ghost stories and unsolved mysteries, and Gilda has problems of her own. Why does her soon-to-be stepdad keep calling Mrs. Joyce by his ex-wife's name? And why is Mrs. Joyce acting like she's possessed? With only a few short days before the wedding, Gilda knows this much for sure: It's going to take every ounce of her sleuthing skill and psychic savvy to solve this one!
