Dils, Tracey E. You Can Write Children's Books. Cincinnati: Writer's Digest Books, 2009.
As I am currently working on a young adult novel, I found this book to be very helpful and insightful. If you have ever considered writing a children's book - from a picture book for young children to a novel for teenagers - I recommend this book. The book contains tips for writing to each age group as well as advice for getting your work published.
