I am addicted to contests!  Even though I never win anything, I keep on trying!  I’ve wasted nearly two hours this morning, Tweeting, Following, and scouring the web for dang contests!  Just full of energy from my breakfast of bacon, and Valentine chocolates one of my little kindergartners gave me.  Anyway, here are two great contests you can benefit from.  The first one, from author Shelli (who I was so excited to learn has written a MG book with angels!  Out on submission now!) has week long prizes with an awesome grand prize whether you are agented yet or not!

The other is from author Elana Johnson elanajohnson.blogspot.com/
Both offer critiquing prizes!  Speaking of, you still have a couple days to bid on the manuscript critique auction from new agent  !

Good luck!!!
