It's been a while since my last UX book review. I hope to find the time to go into detail on the following titles, but for now I'll simply recommend them with a few notes. Many of these books were Chicago UX Book Club selections. If you are local, consider joining the discussion!
Agile Experience Design: A uniquely detailed attempt to integrate experience design into the agile process.
Designing for the Digital Age: This is a fantastic handbook for practitioners.
Open Here - The art of instructional design: A fun collection of visual instruction.
Seductive Interaction Design: How to motivate users with the principles of seduction. Some nice examples here.
Sketching User Experiences: Instruction and exercises for various sketching methods used to facilitate design.
Understanding Comics: The history of comics and how we understand visual language.
