Whodunnit.

Follows Tess Klein, whose life was supposed to follow the plan: love by 25, marriage by 30, baby by 34. But after a spectacularly failed marriage proposal and one wild rebound weekend where her best friend Kelsey tells her “the only way to get over someone is to get under someone else,” Tess finds herself pregnant — and clueless about who the father is. As she sets out to solve the mystery, she discovers that sometimes the right family finds you.
