What if the most terrifying person you know is your ten-year-old sister?

Seventeen-year-old Aussie Che Taylor loves his younger sister, Rosa. But he’s also certain that she’s a psychopath—clinically, threateningly, dangerously. Recently Rosa has been making trouble, hurting things. Che is the only one who knows; he’s the only one his sister trusts. Rosa is smart, talented, pretty, and very good at hiding what she is and the manipulation she’s capable of.

Their parents, whose business takes the family from place to place, brush off the warning signs as Rosa’s “acting out.” Now that they have moved again—from Bangkok to New York City—their new hometown provides far too many opportunities for Rosa to play her increasingly complex and disturbing games. Che’s always been Rosa’s rock, protecting her from the world. Now, the world might need protection from her.

What reviewers said

A Kirkus Reviews Best Teen Book of 2016
A Publishers Weekly Best Young Adult Book of 2016
"[My Sister Rosa is] amazing . . . It's a permanent presence in my life now . . . [Justine Larbalestier’s] brain is an amazing and terrifying instrument."
John Green, author of The Fault in Our Stars
“The evil in the room across the hall, the evil in the flowery party dress, the evil who just wants a bedtime story—Rosa is more frightening and more adorable than any villain you have yet met. Larbalestier is at her tricky, terrifying best in this novel.”
E. Lockhart, New York Times bestselling author of We Were Liars
"Troubling, thoughtful, provocative, and wise, My Sister Rosa is a compelling character study, a chilling thriller, and a love letter to the diversity and vibrancy of New York City."
New York Times bestselling author Kass Morgan
"With My Sister Rosa, Larbalestier brings us a novel that starts out as a quirky family story with a cast of intriguing and likeable characters (even the titular pyschopath), but which quickly races into psychological thriller territory that meets and beats The Silence of the Lambs for suspense—it's the kind of book that had me literally gasping aloud as it rattled to its incredible conclusion."
Cory Doctorow for BoingBoing.com
My Sister Rosa is a gripping, terrifying, wonderful story that I could not put down.”
Laurie Halse Anderson
"Beats The Silence of the Lambs for suspense—it's the kind of book that had me literally gasping aloud as it rattled to its incredible conclusion."
Cory Doctorow, New York Times bestselling author of Homeland
