A Mouse Called Miika is a middle-grade children’s book in the Christmas series by British author, Matt Haig. Miika, the 101st son of (very tired) Ulla and (deceased) Munch, departed the tree hole where he was born without a name. After discovering how hard it was to survive in The World Outside, he was overjoyed to inhabit the cabin deep in the woods of Finland where Joel and Nikolas eked out a living. He was equally happy to join the quest Nikolas made to the Far North, and very satisfied to be living near Elfhelm in a tiny cottage with the Truth Pixie, where Loka the elf occasionally gives him cheese.

But Nikolas is busy with Elf Council business, and he really wants a friend, so he’s glad to have found another mouse, Bridget the Brave. But Bridget criticises his mouse-ness, and challenges him to be brave: she doesn’t want a coward for a friend. This leads to a foolish act in which he is drimwicked at the point of death, something of which the elder elves highly disapprove. His resulting powers, when revealed during an attack by the Snow Owl, see Bridget cosying up to him with a plan she labels “an adventure”. Miika goes along with it, against his better judgement, and the result is almost catastrophic.

Haig’s characters display plenty of flaws and weaknesses, and he uses the nasty Bridget to demonstrate emotional blackmail and gaslighting. Several of his characters, including the Truth Pixie, have wise words and good advice for Miika so that he learns what courage really is, and how he can choose to be true to himself. She tells him: “it is better to be disliked for being who you are than to be liked for who you are not. Being who you are not is exhausting.” Haig’s highly original tale is enhanced with charming illustrations by Chris Mould. Once again, delightful.
