The final collection of four brand new utterly horrid stories; Horrid Henry's Bake-Off sees Henry and Margaret go head-to-head in a hotly contested baking competition, Henry triumphantly reveals his top tips in Horrid Henry's Extra Horrid Guide to Perfect Parents, he reads an interesting book about Evil Evie, a really naughty girl not too dissimilar to himself in Horrid Henry's Bad Book, and conjures up an ancient cannibal's curse to deal with his enemies and small, annoying brother in Horrid Henry's Cannibal Curse.

Horrid Henry is illustrated by Tony Ross, who also illustrates David Walliams' children's books, as well as his own picture books.
