A little rain. A very good read.

Almost excellent. A second edition could easily push it to five stars.

I bought this on a whim after seeing it mentioned in a forum thread, and I am glad I did. I appreciated the honesty about what the book does not cover — it saved me from expecting things that were not there. I particularly liked the way the author builds up from simple cases before introducing the harder material. The examples are small enough to type out and experiment with, which is exactly what I want from a book like this. Four stars, and I suspect a second edition could easily push it to five.

Useful in parts. Fine as a reference, less so as a cover-to-cover read.

I read this over a couple of weekends alongside a small side project, which turned out to be the ideal way to approach it. The exercises at the end of each chapter are worth doing — they caught a few misconceptions I did not know I had. I found myself making notes in the margins, which is always a good sign. Useful as a reference, less so as a straight read from cover to cover.

Some sections were excellent and others felt like filler.

I had been on the fence about this one for a while, and I should have bought it sooner. The author clearly knows the subject deeply and has thought hard about how to teach it. The index and cross-references are surprisingly good, which matters for a book I will come back to. The chapters on game development are the strongest — the examples are stripped down but complete, and I could follow along without constant guessing. Useful as a reference, less so as a straight read from cover to cover.
