Hands down the best ebook of 2011, if you're going to read anything from this list it should be THIS.
The series (Celestra), which seems to get better the further you read into it.
Perfect chick lit, although certain...issues seem to have made it less appealing for me.
A great fantasy duology from Sherwood Smith, a must for YA fantasy readers!
Seriously, these books are amazing (and cheap! which always helps...), and you should really give any of them a go.
Have an awesome weekend,
