Just as Long as We're Together
This is by far Judy Blume's best book in my opinion. The book deals with three girls who are best friends. Rachel and Stephanie have been firends forever when a new girl, Allison joins their twosome. There is some jealousy on Rachel, the brain & musical talent, as she feels Steph and Allison havign more in common.
The book deals with sibling issues (Rachel's "bad boy" brother), divorce (Steph's parents separate), and adoption (Allison is adopted & her mom becomes pregnant).
This is an excellent book that deals with all the issues that girls go through in a realistic manner. It's the kin of book that makes you laugh, cringe, and cry.
