There will be a series of drawings for a signed paperback edition of Tympanum (when released). Next deadline is September 1st, 2016 by midnight! Here's how you enter:
 Send an email to email@example.com indicating that you are going to write an Amazon review, for Exoskeleton OR Tympanum OR BOTH (gets you two entries), and include your Amazon handle/nickname.
 Write and post the review at Amazon. When it appears, you will be entered in the drawing!
 Bonus entries: some people don't know that you can post reviews on other Amazon sites (i.e., you can post the same review on Amazon.uk, Amazon.com, Amazon.ca, etc.) … you just need to log in with your usual username and password. Each review posting will count as an additional entry for the drawing!
