"TL;DR

* I bought my first ebook from amazon
* Amazon's Kindle Android app was really buggy and crashed a bunch
* Tried to download my book to use with a functioning reader app
* Realized Amazon no longer lets you do that
* Decided to reverse engineer their obfuscation system out of spite
* Discovered multiple layers of protection including randomized alphabets
* Defeated all of them with font matching wizardry"

Excellent work!
