Apart from being sisters and living in Dublin, Nessa, Cate, and Bree Driscoll couldn't be more different. Nessa's the happy homemaker, tending to her doting husband Adam and little girl Jill and boasting of marital bliss. Cate, a career go-getter with a knock-out wardrobe, lives with her drop-dead gorgeous boyfriend, Finn -- a famous radio host who's about to break into TV -- and never wants kids. Youngest sis Bree -- a mechanic who's happier riding her motorcycle than chasing guys -- is the free spirit of the family, the one who'll never settle down. No wonder they bicker all the time.

In one way they're the same.

When Nessa begins to suspect that Adam isn't the faithful man he seems, all three sisters are shocked. But with the perfect sheen of Nessa's life finally chipped, Cate might just allow herself to admit that things with Finn aren't exactly wonderful either. And, as her two older siblings debate loving and leaving and kicking their men to the curb, Bree dares to embark upon a relationship of her own. Soon all three sisters face unexpected revelations that will show them that they can all stand on their own two feet if they have to...and that they've got each other to lean on no matter what.
