I just finished a set of 3 books about a motorcycle guy who was part of an outlaw MC, and got saved in prison, and became the 'Outlaw Preacher'. The series by John Andrews talks a little about the MC lifestyle, but all were really well written. The 3 books are titled, 'The Outlaw Preacher', 'The Outlaw Preacher-The Miracle', and 'The Outlaw Preacher-Redemption'. Got them off Kindle, and even got my wife to read them, which she really enjoyed, too.
I have subscribed to a couple websites which send me emails every day with cheap or FREE e-books, which you can get from different sources. Some are only from Amazon, and others are available also from Kobo, Nook, etc. OHFB.com is probably the best I've dealt with so far. They have DOZENS of e-books for FREE, EVERY day! You can also select which genre of books you want to be notified about. BookBub.com, ManyBooks.com, and eBookDaily.com are other ones that are also good. Sometimes I will get a book for Free from one email, and it will then be offered the next day or week from one of the other sites, and sometimes I will only see it for Free on ONE of these sites/emails, but the others will have it for a cheap price. This is the reason I use ALL of them, because I have been able to gradually over time get entire series of books, sometimes from some rather 'big name' authors, ALL for Free! I highly recommend this method for getting your reading fix as cheaply as possible.
