How does a writer decide which story they are going to work on? What makes them choose, out of all the ideas in their head, one specific one to work on and devote all their energy to?
From my perspective, it is all about timing. Sometimes there is something going on in the world that a writer has to respond to or interpret. Kind of like the 2011 novel, When She Woke by Hillary Jordan. That book is a take on the anti-abortion sentiment in the United States, which is relevant to many in recent years.
Or perhaps someone has something to say, such JRR Tolkien when he wrote The Lord of the Rings trilogy. Supposedly, he was inspired by the events of WWI, which he fought in, as well as his take on male friendships, which he supposedly felt was too fractured.
Or some writers pay attention to trends. A few years ago, BDSM erotica books were all the rage, thanks to the Fifty Shades of Grey Trilogy. At the same time, YA dystopian books were widely popular, and there were many different books of that genre.
Or quite simply, a writer is inspired by a muse, and they have to get that story out. No matter the trends, no matter what is going on in the world. There is something in their subconscious that is forcing words to get to paper, or a computer screen. Sometimes the muse chooses what book to write, not the author.
How about you? Who or what inspired you to write your most recent work?
