I can't believe I'm writing a thriller. I don't read 'em...don't watch 'em. But here I am writing one. It just happened. I had an idea of a story, was sure it would turn out to be Literary Fiction just like my first book.
At the outset my protagonist only reacts to events; at some point, however, she embarks on an attempt to take charge and overcome circumstances.
The way it turned out to be, the growth of the protagonist is from ignorance to knowledge, accomplished through a series of progressively more intense and important conflicts. These lead to a climactic conflict and the resolution of the story.
I’m almost 200 pages into the story. Yay me.
