What’s it about?

The story.

Eleven-year-old Mari loves her life, and she isn't sorry about it. She adores fashion and food, delights in time with her two mothers, and has a brilliant time with her friends. But the other witches in her town disapprove: a truly wonderful witch, they say, should always put the needs of others before herself, and Mari cares far too much about her own happiness. Mari, though, doesn't much mind what other people think of her. So when disaster strikes the town, it falls to this most unwonderful of witches to convince the others to find the courage to break free of what they're supposed to be, and to discover magic that works for everyone. Asako Yuzuki, the acclaimed author of Butter, makes her children's debut with a warm, funny and quietly rebellious story about self-acceptance, community and being unapologetically yourself.

About the author

Asako Yuzuki.

AY

Asako Yuzuki

Writer · Japan · b. 1981

Asako Yuzuki is a Japanese author, born in Tokyo in 1981, best known internationally for her adult novel Butter, a bestseller and Waterstones Book of the Year in 2024. Mari the Unwonderful Witch is her first book for children: a warm, funny and quietly rebellious fantasy about a food- and fashion-loving young witch who refuses to accept that a good witch must always put others first. As in her writing for grown-ups, Yuzuki takes appetite, pleasure and being unapologetically oneself seriously, wrapping big questions about self-acceptance and community in an accessible, playful story. A promising crossover from a major literary name, her children's debut is a good bet for readers who like their magic warm-hearted and their heroines refreshingly themselves.
