1) "The Agency 1: A Spy in the House" by Y.S. Lee

Introducing an exciting new series! Steeped in Victorian atmosphere and intrigue, this diverting mystery trails a feisty heroine as she takes on a precarious secret assignment.
Rescued from the gallows in 1850s London, young orphan (and thief) Mary Quinn is surprised to be offered a singular education, instruction in fine manners — and an unusual vocation. Miss Scrimshaw’s Academy for Girls is a cover for an all-female investigative unit called The Agency, and at seventeen, Mary is about to put her training to the test. Assuming the guise of a lady’s companion, she must infiltrate a rich merchant’s home in hopes of tracing his missing cargo ships. But the household is full of dangerous deceptions, and there is no one to trust — or is there? Packed with action and suspense, banter and romance, and evoking the gritty backstreets of Victorian London, this breezy mystery debuts a daring young detective who lives by her wits while uncovering secrets — including those of her own past.

2) "The Twin's Daughter" by Lauren Baratz-Logsted

Lucy is stunned when her mother's identical twin sister shows up at the front door. Separated at birth, the twins have led dramatically different lives and Lucy's mother, Aliese, will do anything to make it up to Helen. But Lucy soon suspects that Helen enjoys being mistaken for her mother a bit too much. Then, on New Year's Day, Lucy finds her mother and aunt tied to chairs in the parlor. One has been brutally murdered--but which twin has died?

3) "Wrapped" by Jennifer Bradbury

Agnes Wilkins is standing in front of an Egyptian mummy, about to make the first cut into the wrappings, about to unlock ancient (and not-so-ancient) history.

Maybe you think this girl is wearing a pith helmet with antique dust swirling around her.

Maybe you think she is a young Egyptologist who has arrived in Cairo on camelback.

Maybe she would like to think that too. Agnes Wilkins dreams of adventures that reach beyond the garden walls, but reality for a seventeen-year-old debutante in 1815 London does not allow for camels—or dust, even. No, Agnes can only see a mummy when she is wearing a new silk gown and standing on the verdant lawns of Lord Showalter’s estate, with chaperones fussing about and strolling sitar players straining to create an exotic “atmosphere” for the first party of the season. An unwrapping.

This is the start of it all, Agnes’s debut season, the pretty girl parade that offers only ever-shrinking options: home, husband, and high society. It’s also the start of something else, because the mummy Agnes unwraps isn’t just a mummy. It’s a host for a secret that could unravel a new destiny—unleashing mystery, an international intrigue, and possibly a curse in the bargain.

Get wrapped up in the adventure . . . but keep your wits about you, dear Agnes.

The year is 1867, and seventeen-year-old Verity Boone is excited to return to Catawissa, Pennsylvania, the hometown she left when she was just a baby.

7) "Mister Death's Blue-Eyed Girls" by Mary Downing Hahn

Based on an actual crime in 1955, this YA novel is at once a mystery and a coming-of-age story. The brutal murder of two teenage girls on the last day of Nora Cunningham’s junior year in high school throws Nora into turmoil. Her certainties—friendships, religion, her prudence, her resolve to find a boyfriend taller than she is—are shaken or cast off altogether. Most people in Elmgrove, Maryland, share the comforting conviction that Buddy Novak, who had every reason to want his ex-girlfriend dead, is responsible for the killings. Nora agrees at first, then begins to doubt Buddy’s guilt, and finally comes to believe him innocent—the lone dissenting voice in Elmgrove. Told from several different perspectives, including that of the murderer, Mister Death’s Blue-Eyed Girls is a suspenseful page-turner with a powerful human drama at its core.
