For over a century, the Blackwells have protected the town of Hollow Cliff from vengeful spirits. Seventeen-year-old Nev is ready to take over for her ailing grandmother as the town's witch protector - unlike her mother, who left when Nev was a child and never looked back. When a stranger arrives at Blackwell House of Spirits to fill a tour guide opening, Nev reluctantly offers him the job. Nev doesn't trust Cal Murphy. He knows more than he's letting on about Blackwell House - and about Nev herself. But Nev soon learns that she has been lied to her whole life. By following the trail of clues left behind in Blackwell House by her most powerful witch ancestor, Nev uncovers an unspeakable legacy of murder and lies...and realizes that a stranger may be the one person she can trust.
