Book 3 in the 113th Assistant Librarian series, this middle-grade fantasy adventure follows Oliver Wormwood as he faces his most dangerous library quest yet.
Oliver Wormwood is shocked when Library Director Thorne arrives in Blackmoor-upon-Wyvern to take control of the library.
Even worse, the director has noticed that several especially volatile books are missing, so Oliver and Agatha set out to retrieve the overdue titles. Following a trail of retired pirates, apprentice mages and a snail the size of a cottage, will they survive the magical books long enough to return home?
