Horrid Henry and the Mega-Mean Time Machine is a story collection where the title story features Henry either inventing, discovering, or pretending to use a Time Machine. Given Henry’s chaotic personality, the time machine is almost certainly "mega-mean" and leads to disaster, whether he’s trying to cheat on a history test, avoid a punishment, or steal treasure from the past. The stories in this volume combine Henry's typical domestic and school conflicts with a fantastical element, allowing him to cause havoc across historical periods or simply use the imaginary device to torment Perfect Peter. The book is another testament to Henry's boundless, if often destructive, imagination and his constant desire to escape reality's constraints.
