The writer's reference book I have on-hand here is the one I used in high school: The Holt Handbook - 4th Edition. It isn't the most complete or up-to-date thing around. I've decided I need to get a new one and start following it. I have a tendency to ask others for grammar help or try to look online for my answers. I think I'm combining styles. I need to become more consistent!

Any opinions on what would be the best style to choose? The Chicago Manual of Style? Something else? Is there one being used most frequently in YA publishing?
