The Hollow Boy (Lockwood & Co., Bk. 3)

A massive outbreak of supernatural Visitors is baffling Scotland Yard and causing protests throughout London. There are reports of many new hauntings, including a house where bloody footprints are appearing, and a department store full of strange sounds and shadowy figures. Lockwood & Co. continues to demonstrate its effectiveness in exterminating spirits, and so it comes as a great shock to Lucy when Lockwood and George introduce her to an annoyingly perky and hyper-efficient new assistant, Holly Munro. Can the team get past their personal issues to save the day, or will bad feelings attract yet more trouble?

Danger abounds, tensions escalate, and new loyalties form in this third delightfully terrifying adventure in the critically acclaimed Lockwood & Co. series.
