I don't often do this on Speculiction. In fact, I'm not sure I've ever done it. I'm going to in essence write two reviews. The reason is, I'm not sure if Ahn Do-hyun's The Salmon Who Dared to Leap Higher (2024) is a book for children or for adults. The distinction is critical, and I'll start with the positive.
If The Salmon Who Dared to Leap Higher is a book for children, then I can wholeheartedly recommend it. Though it is (awkwardly) framed by an adult trying to deal with feedback to something they have created, it quickly switches into the life cycle story of a salmon. It tells of a young, unnamed silver salmon who is learning about life in the ocean. He meets other salmon in his shoal, falls in love, and eventually makes the freshwater trek upriver to the shoal's spawning grounds. This journey is peppered with metaphors and allegories that link the salmon's circumstances to the basics of human life—growing up, starting a family, making difficult decisions, trying to find your way in a group, etc. It's presented with a strong degree of simplicity so that even the 'birds and the bees' have an aura of innocence. Though the title is a spoiler for the climactic moment, most kids won't connect the dots. <smile> In terms of delivering perennial philosophy on the basic building blocks of human existence, social to biological, this short book covers it in sweet, charming fashion for kids.
