Alyssa at The Shady Glade is having a writing contest! This one looks like a lot of fun, so you really should consider entering. And you have until September! All you have to do is write a poem or short story that retells a fairy tale. Details here.
Tip: If you can't think of any popular fairy tale you want to retell (Cinderella, Beauty and the Beast, etc.,), try reading fairy tale books, because there's a lot out there that you've probably never even heard of!
