Book Covers! Make sure they are relevant for your genre.

I've changed my book covers.

I didn't change them because I didn't like my old covers.  I loved my old covers but a friend pointed out that they appeared to target children.  My books are for young adults.  The first book starts out light but gets dark at the end with some torture/violence.  As the characters grow in each series, the dialect matures, the plot becomes more complex and the fights are more than a little bloody.  I think my new covers are more relevant for my genre...at least I hope so!  Sales have picked up so I guess my friend was right.  Thank you!
