The Stonecutters Billionaires is a series of six standalone books that can be read in any order. They are connected because the male protaganists-a group of hot, alpha male billionaires, some badder than others-were at one time in a secret fraternity (The Stonecutters) together. All of the books are standalones, but are loosely connected--each main character shows up in another book before he gets his own story. Readers have fun reading the books and trying to guess who might be the main character of the next book.
