Natalie and Rob couldn't have less in common. Nat's a messy artist, and Rob's a rigid academic. The only thing they share is their devotion to their respective best friends - who just got engaged. Still, unexpected chemistry has Natalie cautiously optimistic about being maid of honor to Rob's best man. Until, minutes before the ceremony, Nat learns that Rob wrote a one-star review of her new novel, which has them both reeling: Nat from imposter syndrome, and Rob over the reason he needed to write it. When the reception ends, these two opposites hope they'll never meet again. But, as they slip from their twenties into their thirties, they're forced together whenever their fast-track best friends celebrate another milestone. Through housewarmings and christenings, life-changing triumphs and failures, Natalie and Rob grapple with their own choices - and how your harshest critic can become your perfectly imperfect match. After all, even the truest love stories sometimes need a bit of rewriting.
