The Billionaire’s Rules series by Kelly Favor includes 16 installments all published in 2015. Each book has a single-word title (Discipline, Consequence, Truth, Lies, and so on), and together they tell one continuous billionaire romance story.
The rapid publication schedule, with all 16 books released in one year, is typical of Favor’s serial approach to romance publishing.
