Life Sentence follows Stella, a girl who has spent the last eight years living like she was dying (because she was). Just like the "manic pixie dream girl" heroines in her favorite sappy cancer movies, Stella traveled the world, faced her darkest fears and found true love on a whirlwind trip to Paris. But when Stella finds out that her cancer has been cured, she is suddenly forced to face the long - term consequences of the "live in the moment" decisions she made, including marrying a total stranger.
