An old friend of our family, an exuberant lady of advanced years, once told us that she would eat a bar of soap if there were enough salsa on it. Books on how to write are the salsa for me, and so yes, I read a book on how to write a Christian romance. I read Stephen King's book on writing too, despite never having read anything else by him.
So I rated this one three stars. The wordcraft portions of this book were quite good, and very helpful -- particularly on that pesky POV cluster of problems. But the examples, culled from various Christian romances were enough to put me off my feed, and hence the three stars.
