The library has just finished editing their publication, Christian Fiction Authors. You can pick up a copy at your local branch. It lists hundreds of Christian fiction authors and the series of books they have written. Series are listed by name, and the titles are in order so you can follow the story from beginning to end. The catalog is so nice because you can mark what books you have read and make notes about your favorites.
I picked up a wonderful book not too long ago titled Relentless by Robin Parrish. Reading the flap, it sounded like the author took a comic strip and just turned it into a novel. As I began to read through it, I realized this was the best description for the book.
