Any Kindle suggestions?

I’m becoming a regular high-tech kind of guy, though at least I’m a late adopter.  I now have a Kindle.  (My wife wanted one for Mother’s Day, so I obliged, whereupon since I was always borrowing hers, she bought me one for Father’s Day.  Our devices are hooked up to the same account so that when either of us buy a book it is “archived” on the other’s device, allowing us to download each other’s books for free.)  I carry around with me some 22 books and they don’t weigh a thing.  That makes it great for the traveling I have been doing lately.  The device will even read the book aloud to you, in a technology I do not understand.  (If anyone does, please explain it to me.  Also explain how the voice feature on my GPS device–see!  more technology!–works.)  That makes it a good treadmill companion, helping me not be  so bored as I pursue physical health.  Then I learned that I can increase the size of the type so that I can read it myself on the treadmill.

I can’t say I don’t prefer paper, but I’ve gotten used to reading on the Kindle.  In addition to reading what I consider “fun” books, I have downloaded some great classics for free or nearly so, including volumes of the complete works of G. K. Chesterton (one of my favorite writers of all time, but who has written lots of stuff I haven’t read yet) and Agatha Christie.  Also the complete Sherlock Holmes stories.  And I love my The Lutheran Study Bible on Kindle, which is set up so that you simply click the passages to read the notes, all in big and readable print.  Also my Treasury of Daily Prayer.  (Click the links to get them yourself.)

Many writers are finding that they can make their books available through Kindle directly without going through a publisher, taking all of the money themselves while also making their books cheaper for their readers.  The problem is, a publisher vets books, keeping out those that are unreadable, and also makes people aware of them.  It’s thus hard to know about worthy books that are electronically published, except by word of mouth.   So let’s have some word of mouth.

What are some good Kindle titles that you would recommend?
