Twisty Little Passages, by Nick Montfort

Twisty Little Passages is "an approach to interactive fiction" (aka IF, i.e. Infocom-style text adventures). I remember when the book came out, thinking, "Cool idea. I need to get this book. Er, $30? Maybe I can wait." Well, a pb exists, and cheaper still is the electronic text, which I read on my kindle.
