I wouldn't buy a Kindle if you paid me to buy one. I got so turned off when the eReaders were first introduced. My first eReader was a Sony eReader and books were free from the library using Overdrive. At the time, Amazon was pushing the sale of the Kindle and then charging for any books you wanted to read. Eventually they gave in and started sharing free ones. Now with the Kindle app, one can still download Kindle format books from their local library. The Free Library of Philadelphia is a great library.
I used to read every James Patterson book that he wrote. Then he started sharing the writing with other authors. As a result is books now are a hit or miss. The only series he has that doesn't seem to have suffered from that manner of writing is the Women's Murder Club series.
John Grisham was good for his first couple books and now they are not so much. I just tried to read his Camino Winds book and after getting through a third of it, I returned it to the library.
That's the other neat thing about borrowing from the library. I can return the book if I don't like it and it hasn't cost me anything.
I tend to stick to fiction. I spent about 10 years as a legal secretary and after proofreading tons of legal docs. I really don't care to read any non-fiction. Since the pandemic came into our lives I find myself leaning more towards what are known as "beach" reads with pleasant endings. And Just finished Thick as Thieves by Sandra Brown.
