Zach, Poppy, and Alice have been friends forever. And for almost as long, they’ve been playing one continuous, ever-changing game of pirates and thieves, mermaids and warriors. Ruling over all is the Great Queen, a bone-china doll cursing those who displease her.

But they are in middle school now. Zach’s father pushes him to give up make-believe, and Zach quits the game. Their friendship might be over, until Poppy declares she’s been having dreams about the Queen—and the ghost of a girl who will not rest until the bone-china doll is buried in her empty grave.

Zach and Alice and Poppy set off on one last adventure to lay the Queen’s ghost to rest. But nothing goes according to plan, and as their adventure turns into an epic journey, creepy things begin to happen. Is the doll just a doll or something more sinister? And if there really is a ghost, will it let them go now that it has them in its clutches?
