The theme of the Young Adult Summer Reading Program is “Spark a Reaction.” Registration for students entering grades 6-12 in September opens June 2 at the Leach Library main desk. The program runs June 2 – Aug. 14. For every book of at least 80 pages read by 8 p.m. Aug. 11, participants can complete a raffle slip for a prize drawing. Students entering grades 6-8 at Londonderry Middle School who read 12 books by Sept. 6 earn a certificate to give to their English teacher for extra credit or a homework pass. The program includes evening meetings and movie nights.
