There are a few things you should know about Baylor Bosco: He's thirteen years old, he has a twin sister, and he really does NOT like ghosts...which is problematic because he's a medium and sees ghosts everywhere.

Oh, and his twin sister, Kristina? She's a ghost too.

They've been working as a pair for years, expertly relaying messages from ghosts to their still-living loved ones. Baylor's even managed to come up with an introductory phrase--one that he has to use far too often.

But when a strange ghost shows up close to Halloween, a grown man, covered in a sheet, with only his black leather shoes showing from the bottom, Baylor starts to wonder if something else has taken notice of him. And when his sister goes missing, somehow ghost-napped, he's forced to figure out the truth about the Sheet Man and his sister's disappearance, all without help from his usual ghostly ambassador.
