To celebrate she is giving away 5 copies of her upcoming UK release To Defy a King.
Speaking of To Defy A King, Alaine from Queen of Happy Endings is coordinating an Around the World tour for this book, so if you want to read it now instead of waiting for it to be released in other countries (maybe), then head on over and sign up. There are a strictly limited number of places so be quick.
Allie from Hist-Fic Chick attended an author event for Stephanie Cowell, and has shared some videos that she took for those of us who couldn't attend.
