Just release any book that is predominately BLUE in colour or has a shade of BLUE in it's title....simple eh?
Join in at anytime - if you are releasing as part of another challenge & the book is BLUE why not include in this challenge too? :o)
There will a prize of wings for a month. Everyone who makes a release for this challenge will get their name added to the draw & you can have an extra entry for every 10 books released :o)
