‘There is madness in it.’‘Yes. But magic too.’Following the death of their parents, Jessie and her older sister Kay move to their grandmother’s abandoned house. One night they discover The History of Mischief hidden beneath the floor: it is like no book they have ever seen.From Ancient Greece to war-torn China, from the Ethiopian Empire to Victorian England, the pages reveal a world of mischief and mystery, adventure and adversity – stolen bones and fiery dragons, feisty philosophers and tempestuous tyrants, shape-shifting trees and scorched scrolls.But not everything is as it seems, in the book or in her life, and Jessie is determined to find the truth. The History has a history of its own. Unravelling its secrets might be the biggest mischief of all.
