My very short and very well received book (26 all 5-star reviews and counting, hooray!), The Texas Medical Jurisprudence Exam: A Concise Review, is now available on iTunes/iBooks and Kobo in addition to Amazon. Additional ebook formats and the print version are forthcoming. 
While I personally use Amazon for just about everything, I know some people prefer to use other ebook vendors or non-Kindle readers. While the book was part of the KDP Select program (Kindle Unlimited etc), it was exclusive to Amazon. I’ve decided to not renew that program membership (more on that later), which allows me to open up the book to other markets for those so inclined.
For the time being, Kobo is offering a $5 credit for your first ebook purchase, which means that if you’ve never gotten an ebook from them before, my book would be half price.1
