The Outermost Mouse by Lauren Wolk & Kristen Adam

I am having a lot of THOUGHTS about this book that have me trying to second guess my younger self, and it is a WEIRD experience.

This children’s picture book is about a little mouse who inhabits the Outermost House, a cottage on a section of beach that juts out into the sea, alongside the old man who lives there too. The place is beautiful, providing the little mouse with everything she needs, but it’s also in danger. Every day, the sea eats away at the shore, getting closer and closer. The little mouse decides that she has to do something to stop this encroachment and save her house from destruction.

My dilemma after reading this is that I can’t decide whether my younger self would have bought into the ending that Lauren Wolk gives us here. It is heroic and adventurous but also, I fear, deeply untrue in a way that I believe even my younger self would have recognized. Frankly, I am a little scarred as an adult from having read this, and console myself with the thought that in real life the little mouse would absolutely have just dug out a hole for herself in a less endangered inland area and lived the rest of her short and happy natural life out by the beach she so loved.

But maybe kids will read this and be inspired by this thing of beauty and write their own ongoing adventures for the little mouse. That said, I do think that the language may be challenging for the usual picture book crowd, who will likely need help with sentences like “But when the sun began to blush with dusk, she had managed only the smallest of barricades.” It’s poetic, but definitely feels like it was written for advancing readers.

The art, however, is note perfect, with some of the most beautiful picture book illustrations I have ever seen. The endpapers especially are astonishing in their harmony of line and color. I literally opened the cover then had to stop and stare at the composition of beach wrack Kristen Adam had designed. It’s gorgeous, showstopping stuff.

Inspired by Henry Beston’s non-fiction classic of nature writing The Outermost House, this children’s book brings its predecessor’s themes to a younger, more modern audience. I’m still not sure how much I liked this book, but there’s no denying how beautiful it is, or how well-meaning.
