The Joker's on You

By Lisi Harrison and Daniel Kraus

The Graveyard Girls navigate an evil smart home, public humiliation, and turbulent middle school friendships in this consuming fourth installment by New York Times bestselling authors Lisi Harrison and Daniel Kraus.

The Graveyard Girls are back together but they've never felt further apart. The excitement of finding Silas Hoke's bones quickly fades as tension between the five friends threatens the future of their beloved club.

Frannie secretly struggles with life-changing news and unexpected Internet fame. Sophie betrays her bestie to get ahead. Gemma's plan to win Zuzu's love backfires. Whisper can't balance her new friendship with Paisley, her old one with the Graveyard Girls, and her latest crush. And Zuzu's Spirit Squad summons her to find out what--or who--has possessed Frannie's new "smart" house.

Can the fighting friends put their differences aside and banish the evil force threatening Frannie's home? Or will their club--and lives--be gone for good?

Fans of author Lisi Harrison's Monster High books and Daniel Kraus's Trollhunters will devour this clownishly creepy installment in the Graveyard Girls series. Young readers looking for scary stories for kids ages 8 to 12 will delight in this frightfully fun mystery series.
