From the back cover

"Since its inception in 2005, Qi has generated great interest over the
internet.  Here for the first time is the hardcopy exposition of the
language, remastered for the issue of Qi II in 2008.  This second
edition fixes the language standard for Qi.

The book is both a comprehensive introduction to Qi and to functional
programming.  The first half of the book covers foundational material
and is suitable for an undergraduate introduction to functional
programming.

The second half of the book explores the theoretical foundations of
Qi,
including lambda calculus, type theory and logic programming and
concludes with Qi applications in computational logic and expert
systems."

This book covers a complete exposition of the Qi II language in 440
pages and can be ordered through Lambda Associates.
