This is a competition from Melinda Salisbury Login To Enter »

READERS. The superlative @Lauren_E_James and I both gifted you with new releases yesterday and we have teamed up so one of you can win them! You need to RT and follow both of us for a chance to win both books, and a set of pins. UK only. Ends midnight Sunday March 17th.

Sometimes promoters tweet more than once.
Tweets will only get updated when you re-fetch them. This helps you because competitions will no longer "jump" between pages when competitions get added or competitions finish while you are browsing them. Competitions get "fetched" when you login or manually re-fetch them with "Forget Ended Competitions & Fetch New Ones". Additionally hidden tweets will stay visible until you "fetch" to save reloading the page and save you from losing your position.
