I have a book coming out about interactive fiction in general and Twine specifically in another two weeks or so, published by Pearson. Chris Klimas (http://chrisklimas.com/writing-interactive-fiction-with-twine-ebook/
) tech edited it. It has been an enormous labour of love for the last year or so, and the fact that it is almost out (well, the e-book version is out this week, but the paper version will be in bookstores on May 19th) is blowing my 9-year-old self's mind. My dream when I was a kid was to find someone who loved Zork as much as I did. And now I'm an adult and I get to hang out online (and offline -- we have an IF meetup) and talk about interactive fiction. And write a book about interactive fiction. That blows my mind.
So the book is about 50% Twine 2, covering almost every macro in Harlowe and then SugarCube, and 50% general information on constructing interactive fiction in general. Building believable characters, developing arc, creating vivid setting -- all the things you need to think about regardless of which tool you use -- are in here. My background and MFA is in fiction. Chris's post above sums up the book well.
We would love any help in publicizing the book to the greater world. Tweet it, Facebook it, throw it up on other forums. Any and all help is appreciated. Thank you enormously to everyone who has already done that.

Yikes -- I can't believe I have a new book coming out in a few days.
