Tam Lin, by Pamela Dean, fiction. Pros: Captures much of the spirit of going to a liberal arts college and figuring out what you want to do with your life (the protagonist is an English major who wants to go to grad school and eventually teach and/or write poetry). May cultivate an infectious love of classic literature. Cons: Includes a pregnancy and an abortion decision as a major plot point, which may not be in accord with your family values. Somewhat dated (takes place in the 70s).
