Old flames are reignited in the fifth and final book in the New York Times bestselling Jessica Darling series.

Captivated readers have followed Jessica through every step and misstep: from her life as a tormented, tart-tongued teenager to her years as a college grad stumbling toward adulthood. Now a young professional in her mid-twenties, Jess is off to a Caribbean wedding. As she rushes to her gate at the airport, she literally runs into her former boyfriend, Marcus Flutie. It’s the first time she's seen him since she reluctantly turned down his marriage proposal three years earlier–and emotions run high.

Marcus and Jessica have both changed dramatically, yet their connection feels as familiar as ever. Is their reunion just a fluke or has fate orchestrated this collision of their lives once again?

Told partly from Marcus’s point of view, Perfect Fifths finally lets readers inside the mind of the one person who’s both troubled and titillated Jessica Darling for years. Expect nothing less than the satisfying conclusion fans have been waiting for, one perfect in its imperfection. . . .
