Welcome to the first of PW's monthly self-published bestseller lists, powered by Smashwords. Each month we'll be bringing you a list of the 25 top-selling titles published in the Smashwords platform, which are distributed to Amazon, the Apple iBookstore, Barnes & Noble, Kobo, Sony and Diesel.

Romance features heavily in our inaugural list, with 18 of the 25 top-grossing titles coming from the romance and erotica categories. Three authors -- Katie Ashely, Abbi Glines, and Shayne Parkinson -- each have three titles on the list, and only two titles are priced above $3.99. How do you sell a lot of your own e-book? Write a lot, and sell at a low price.
