The Soul in the Bell Jar
When 11-year-old Lindsome's self-absorbed parents take a trip around the world, she is sent to live with her great-uncle in his remote, crumbling estate. And the rumors about it are true: her uncle, the half-mad scientist Professor Dandrige, lets his gruesome, undead experiments wander the grounds. But the rotting animal corpses that move in the dark are the least taboo of the estate's secrets, and Lindsome will need to unravel each one to stop the Professor's most nightmarish experiment of all.
