The program, open to ages 18 and beyond, is held every year during the winter months, and rewards readers for doing what they love to do – read. Participation is simple: sign up at your local library, and pledge to read at least 12 books during the 3-month long program. Most readers will meet that goal and many will exceed that number. Most PCLS libraries offer patrons who complete the challenge an incentive prize. In addition, libraries will be given recognition for various distinctions including the most new participants enrolled in the program and most books read throughout the three-month period.
