It's May of '68 in New York City, and twenty-two-year-old Freddie Riley is cycling home from her job as a bike messenger, unaware that her life is about to be upended. She walks into her apartment to find a stranger, lying dead, and her foster mother, Yvette, bleeding out on the floor. Yvette whispers a cryptic message that sets Freddie and her best friend and secret crush, Celia, on the run, careening from gritty old Times Square to the glamorous Cary Grant suite at the Warwick.

Freddie unleashes her considerable street-smarts and ingenuity to keep them one step ahead of their relentless pursuers, with the hope they can solve the mystery of Yvette's murder before they both end up in serious, possibly deadly, trouble.

Race against time alongside a feisty heroine with a kickass attitude through the rough streets of 1968 New York City in a tale where the murder is only the first thread of a secret everyone wants to keep buried forever.
