This Lullaby, by Sarah Dessen, is all about decisions.
Remy never knew her biological father, but she had a steady stream of step-fathers (five in all). She spent her high school years trying to find happiness in an endless number of temporary boyfriends.
Ever fearful of falling in love, Remy never allowed her relationships to last longer than a couple of months. When Remy found Dexter, a boy that had the potential of making her fall in love, she got scared and pushed him away.
With the help of a lot of courage, coincidences, and an unfaithful fifth step-father, Remy finally realized what she had lost.
