I found a website Daily Lit which has several books you can get in segments each day. Each book has a different number of segments depending on how long the book is. Each segment can be read in less than 5 minutes. Each segment is emailed to you, you can set when you want to receive the emails.
Many of the books are offered for free. One that I have started reading is "The Art of Money Getting" by P.T. Barnum
