The releases will alternative between the full-number novels (Book 1, Book 2, etc.) and the half-number books (Book 2.5, Book 3.5, etc.).
I'll write a post about these .5 books soon, but here's a quick summary of the idea behind them:
All the main books in the Sorcery and Science series (except Book 1) will be followed by a companion book that lets you dive even deeper into the lives of the characters. In past and parallel events that shape and influence the primary plot of the series, the reader will adventure further into the world of Sorcery and Science.
In other news, I've modified my Books page to make it more visual. You'll also get a peek at the titles of upcoming books still waiting on a cover.
