That feeling when you want one more.

Recommended, with the caveat that it is not a gentle introduction.

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. The index and cross-references are surprisingly good, which matters for a book I will come back to. It is denser than the page count suggests, and I found myself slowing down around the middle. Worth picking up if you already have the basics. Set realistic expectations and you will get a lot out of it.

Decent, but uneven. Some chapters are much stronger than others.

There is a particular kind of technical book that is dense without being difficult, and this is one of them. A few of the examples could be more realistic, but the underlying points come across clearly. The progression from chapter to chapter is well thought out; nothing feels out of order. The exercises at the end of each chapter are worth doing — they caught a few misconceptions I did not know I had. Borrow it first if you can, or at least check the table of contents carefully before buying.
