Together again. It's been a year since Katie O'Roark, Chelsea James, and Lacey Duval shared a special summer at Jenny House. The girls have each spent the year struggling to fit into the world of the healthy. Now they're back, this time as "big sisters" to a new group of girls who also face life-threatening illnesses.

But even as the friends strive to help their "little sisters" face the future together, they must separately confront their own expectations. Katie must decide between an old flame and an exciting scholarship far from home. Chelsea must overcome her fear of romance. And Lacey must convince the boy that she loves that the feelings for him can be trusted.

When tragedy strikes Jenny House, each of the girls knows that things can never be the same again. Will Lacey, Chelsea, and Katie find a way to carry on the legacy of the Jenny House? Can their special friendship endure when they go their separate ways?
