Publisher's Description

To most people, Piper Sail looks like a rich girl with little potential, but she surprises everyone, including herself, when she starts investigating her best friend’s disappearance. Perfect for fans of Agatha Christie and Maureen Johnson, The Lost Girl of Astor Street combines the allure of Jazz Age Chicago with a twisting mystery that will keep you guessing until the very end. Lydia has vanished. Lydia, who’s never broken any rules, except falling in love with the wrong boy. Lydia, who’s been Piper’s best friend since they were children. Lydia, who never even said goodbye. Convinced the police are looking in all the wrong places, eighteen-year-old Piper Sail begins her own investigation into Lydia’s disappearance. With the reluctant help of a handsome young detective, Piper searches for answers in the dark underbelly of 1924 Chicago. Did Lydia get abducted by one of the city’s most notorious gangsters? Or does the trail lead back to their own affluent neighborhood? “Morrill has a keen eye for historical details and setting, making Jazz Age Chicago Piper’s invisible yet omnipresent sidekick. A…well-crafted historical whodunit.” -Kirkus Reviews Piper must decide if she’s willing to risk her life to find out the truth.

“The Lost Girl of Astor Street is a delicious read! Stephanie Morrill gives readers a historical mystery full of heart and brimming with the vibrant atmosphere of 1920s Chicago. The moment I finished, I was ready to flip it over and begin again.”

Shannon Dittemore

“Spunky Piper Sail is more interested in investigating her best friend’s death than in society’s expectations for a young woman in 1924. She’s curious, intelligent, and gutsy, and while she’s not immune to a handsome man, she’s not needy. Reminiscent of Philip Pullman’s Sally Lockhart series in all the best ways! I thoroughly enjoyed The Lost Girl of Astor Street.”

Maureen Doyle McQuerry

“Witty and compelling, The Lost Girl of Astor Street is as thick with romance as it is with evolving mysteries. Piper Sail is a 1920s heroine to root for, and the dashing Mariano Cassano a detective sure to win more hearts than just her own. A truly fresh and engaging story that not only kept me guessing until the very end, but that left me with a satisfied sigh for more please!”

Joanne Bischof

“A fast-paced mystery that sparkles with the sights and sounds of 1920s Chicago. The strong characters and setting drew me in, and the twists and turns kept me hooked until the end.”

Renee Collins

“Step back to a more glamorous time with the captivating story of Piper Sail, a sassy young woman with a penchant for finding trouble. As a mystery unfolds, you'll be turning the pages and cheering on a heroine you won’t forget.”

Jenny B. Jones

“Thoroughly engaging. Fast-paced, filled with vivid details, and featuring a delightful heroine, it was a joy to read. It’s a keeper, for sure.”

Shelley Shepard Gray

“In The Lost Girl of Astor Street, Morrill invites us on a wild ride through teen eyes down the crime-ridden, mob-infested streets of Chicago in the 1920s. Laden with mystery and laced with romance, this intriguing who-done-it read is a testament to friendship, courage, and first love that you won’t soon forget!”
