Just release any book that is predominately BLUE in colour or has a shade of BLUE in it's title....simple eh?
If you are releasing as part of another challenge & the book is BLUE why not include in this challenge too? :o)
And there's prizes!! For every book you release, your name will go in a draw for wings for a month. Two winners will be drawn when all releases have been posted - have fun!
Oh... & don't forget to let us know of any catches :o)
