I've read a few of Francine Rivers books.. they are very good!
The Last Sin Eater, I've had a lot of negative feedback on it, but I liked it
She also wrote the
Mark of the Lion series... EXCELLENT books! They are historical fiction with a little bit of everything else mixed in.
Frank Peretti is good too.
The Prophet was a bit long and drawn out, and I found that I had to really make myself read it at first. But once you get into it, its good.
This Present Darkness was the best one of his though, I think.
