I was due to write a proposal for a new contract and had recently watched Twinsters, about a pair of girls separated at birth.
I was trying to think of a way to make that trope fresh and different. It’s been done by a lot of authors.
As I was thinking about ways that twins might be sent home with different parents, the baby swap idea hit me. I quickly realized that the characters in each book had to have different and significant conflicts aside from the fact their babies had been swapped, especially since the swap is resolved fairly early in the stories.
That’s how Cesar gets amnesia. I thought, “What if he doesn’t even know he had sex with Sorcha?” He finds out when the hospital calls him for a blood test.
He’s pretty darned surprised.
