Covers and titles can draw in readers is you're not an author known everywhere by your name alone. I write my books in series and I try to make the titles not only indicative of the book content but also somewhat connected to the previous books. Lots of authors do this and much better than I do. For instance, does anyone doubt Alex Cavanaugh's upcoming book, Cassafire, is in a series with Cassastar? The titles let you know the books are related without seeing the author's name.
I tried that in my very first romance series, The Chronicles of Solonia. The series started with The Greater Good, followed by The Lesser Evil, A Ruthless Good and the wrap up novel, One Good Woman. The titles weren't perfect matches but they were connected enough to seem like they went together.
Today my clever publisher is running a special on that last book, One Good Woman, at $1.99, as an early promotion for the my next Tiger book coming out in December. One Good Woman is the featured book today at New Concepts Publishing. I hope you can check it out.
Do you write in series and try to give your book titles similar titles? Do you know an author who is exceptionally clever with titles?
