In her senior year of high school, having uncharacteristically drunk too much at a party, Angel Hansen consents to be taken home by a boy she normally doesn’t care much about, and ends up having sex with him. Two months later, with the help of her best friend, Karin, she takes a pregnancy test, finds it is positive, and visits an abortion clinic. Karin, who has had an abortion, is ready to support her in complete secrecy. Tim, the father, is horrified, but consents to pay for the procedure. At the last minute, however, and without being able to explain her reasoning to either of them, Angel decides not to go through with the abortion.

In the ensuing months, she endures her parents’ disappointment, her friends’ distancing, and the loss of a number of hopes, including the Yale education she was expecting. In the course of those months, however, she also finds new levels of relationship evolving with parents, grandparents, and the few friends who decide to engage with her on new terms, including Danny Stanton, a friend she’d grown up with, and had recently come to love in new (but, she thought, hopeless) ways. To her great surprise, Danny asks to accompany her to Lamaze classes, and, after taking her to the prom in her ninth month, sees her through the baby’s birth. The story, told in the first person in the form of journal entries, chronicles a young woman’s process of maturing through the consequences of a mistake into acceptance of responsibility for choices, even one she can’t fully account for.

One interesting scene records a conversation between Angel and Karin where Karin admits that her weeks-long estrangement comes from a feeling that Angel’s choice to keep the baby implies a judgment of her for terminating her own earlier pregnancy. Angel makes it clear that she respects their differences, fosters no judgment, and can’t even fully articulate why she felt strongly about needing to make a different choice, but feels clear and sure about her own.
