So if, for some reason, you find that you are allergic to Amazon or Barnes & Noble (I've been told B&N may contain shellfish), there is a Kobo version: http://www.kobobooks.com/ebook/The-History-Mayan-Ball-League/book-N9KSvI...
If you are Amazon and Barnes & Noble *and* Kobo-averse (I won't ask what they all did to make you so), there's an iBook version with some extra visual material, as you'd expect from something on Apple's store: https://itunes.apple.com/us/book/history-mayan-ball-league/id587278189?ls=1
I would be indebted to you in some deep, preternatural way, if you we're to purchase any of these editions.
