I LOVE to read so here are a few of my favorite authors.
Joanne Fluke-She writes a series about a baker named Hannah Swenson who solves murder mysteries. This is not a christian author, but I have never ran acrossed anything I objected to.
Karen Kingsbury-love her books, but they always make me cry, so if that will bother you just beware. I have ran into people who dislike them because of the emotions they bring out.
Craig Parshall-He writes legal drama like John Gresham, but is christian.
Mindy Starns Clark- christian mystery writer
Brock and Bodie Thoene-Historical Fiction, mostly set around WWI & II. One or two of their series is set in Isreal around the time of the war for freedom in the 60's.
I have a bunch more so if you want more suggestions I can give them to you.
Have fun at the library! It is my favorite place to go, well next to church.
