I hear writers talk about ‘the book of their heart.’ What’s yours?

I really love writing love stories, so my heart goes into every one of my books. The novel that I planned the longest (a decade!) and that was the first book to completely slay me while writing it was In the Arms of a Marquess. When How a Lady Weds a RogueThe Earl and Again, My Lord came along, they affected me the same way. The Prince has turned out to be another novel that in the writing rocked me to my core.
