In the sequel to P.S. Longer Letter Later entitled Snail Mail No More, Tara and Elizabeth continue their correspondence through e-mail. The girls are in eighth grade now, and their lives are changing once again.

Tara's mother is pregnant, and Elizabeth's father has returned and is causing problems in his family's lives. Again, this is an analysis of friendship, as the girls share their joys and troubles and navigate through the ups and downs of life.
