Hazel Lancaster and Augustus Waters, The Fault in Our Stars
First Encounter: Wry sixteen-year-old Hazel meets Augustus, a hot, sarcastic 17-year-old with a crooked smile, at their cancer support group. ''Goddamn,'' Augustus said quietly. ''Aren't you something else?''
Defining Moment: He reads her favorite book An Imperial Affliction.
Relationship Challenges: Hazel's diagnosis is terminal.
Why They Work: Because they both understand what it feels like to be young and sick and still fully, hilariously, passionately alive. Because of Amsterdam. Because they deserved three lifetimes together. Karen Valby
