Holden Caulfield was the characeter in the book "Catcher in the Rye" by JD Salinger.
I never read it, teenage girls usually read "Dear God It's Me Margaret" but I thought it was a must read for teenage boys back in the day.
I am happy to say I know that "Into the Wild" is a must read in lots of middle/ high schools..instead of "Catcher in the Rye"
