Most readers don’t realize that writers are often many months ahead of the publishing cycle. For example, my novel When Darkness Comes was issued in August of 2017.
My fifth novel, a murder mystery set in 1921 Italy called Honor the Dead, was submitted to my fabulous agent in August of 2017, for probable publication in spring of 2018..
And I just finished the rough draft of my sixth novel, a thriller describing an escape from East Berlin in 1961, called For Those Who Dare. Publication is at least a year away.
