This is a mind-bending, rousing adventure celebrating classic ghost and horror stories, by the author ofThe Grimm LegacyandThe Wells Bequest.

Sukie’s been lonely since the death of her big sister, Kitty—but Kitty’s ghost is still with her. At first that was comforting, but now Kitty’s terrifying anyone who gets too close. Things get even weirder when Sukie moves into her family’s ancestral home, and an older, less familiar ghost challenges her to find a treasure. Her classmate Cole is also experiencing apparitions. Fortunately, an antique broom’s at hand to fly Sukie and Cole to the New-York Circulating Material Repository’s spooky Poe Annex. As they search for clues and untangle ancient secrets, they discover their histories intertwine and are as full of stories of love, revenge, and pirate hijinks as some of the most famous fiction.
