This fantasy tale of a child's exile and subsequent monomythic quest to find himself seems to languish in obscurity. Less than 300 ratings for a book this old means it will most likely be entirely forgotten soon, unless some kids tearfully pose with it on TikTok.
Its obscurity is justified: this book is quite the unremarkable fantasy novella.
The prose is sub-par and unrefined, making a barely 90 page book surprisingly baggy. The cluttered sentences and almost conversational tone befuddle and irritate. They often start with conjunctions, mix past and present tenses like oil and water, and frequently employ the descriptor "very much" to make for an aggravating reading experience. There's little in the way of descriptive power or imaginative metaphor, sapping any of the potential fantastical elements out of this "fantasy" novel.
I can enjoy a book with sub-par writing in SFF if its plotting or world make up for it, but alas, this is not the case. There is just so little here: no compelling characters, no unique magic, and a cliched story you've seen elsewhere done much better. Animal companions are predictably employed as a cheap means of stirring emotion, and even THAT doesn't work to gain your sympathy.
Yes, I'm aware this is apparently a children's fantasy book, but Ursula K. Le Guin proved with her exceptional Earthsea series that books written for children can be gripping, and full of imagination. This book reads like a first draft the author meant to expand upon further, but left in a drawer somewhere and decided to publish on a whim. If you see this book for sale, do what the fantasy genre at large has already done: ignore it.
