What are the books that make you cry, yet you'd love to read them again?
In recent memory, mine would have to be PS, I Love You
by Cecelia Ahern.
Off the top of my head, I also cried over Anne of the Island and Rilla of Ingleside (L.M. Montgomery), Flowers for Algernon (Daniel Keyes), Of Mice and Men (John Steinbeck), The Green Mile (Stephen King), The Wild Children (Felice Holman), Tuck Everlasting (Natalie Babbitt), and Summer of My German Soldier (Bette Greene).
Gosh, I cry over so many books!
