Complete rules here.
#FaithPitch happens twice this year, on Tuesday, February 28 and Wednesday, June 28 from 8am to 8pm Central Standard Time (CST)
Each 140-character pitch (sentence) must have the hashtag #FaithPitch in it as well as at least one genre/age group hashtag. The hashtag (#) is necessary because it organize the pitches by category for those monitoring the Twitter feed looking for specific types of books.
Good luck & have fun!
