In 2012, I had an idea for a novel called The Desire Card, which centered around a sinister organization that promised "Any Wish Fulfilled for the Right Price." I'd been speaking to a doctor friend of mine about the difficulty of getting a liver transplant, and an idea gelled: What if someone who'd always been able to get anything he wanted in life desired a liver and contacted an organization to obtain it through back channels? I wrote the book, never imagining I would write four other interconnected novels, and sold it to a publisher who wanted more.
Great, right?
