Admission - Jean Hanff Korelitz

From the New York Times bestselling author of You Should Have Known (adapted as The Undoing on HBO), comes a page-turner about a college admissions officer with a secret—now a major motion picture starring Tina Fey and Paul Rudd.
For years, 38-year-old Portia Nathan has avoided the past, hiding behind her busy (and sometimes punishing) career as a Princeton University admissions officer and her dependable domestic life. Her reluctance to confront the truth is suddenly overwhelmed by the resurfacing of a life-altering decision, and Portia is faced with an extraordinary test. Just as thousands of the nation's brightest students await her decision regarding their academic admission, so too must Portia decide whether to make her own ultimate admission.
Admission is a fascinating behind-the-scenes look at the complex college admissions process and an emotional examination of what happens when the secrets of the past shake a woman's life to its core.
