A teen girl's dream job aboard a luxury train derails when she discovers the strange cargo being transported—a mysterious and beautiful greenhouse—but its flowering façade may hide deadly thorns beneath, in this atmospheric and lush novel from the author of Those We Drown.

Soon, Lara will learn: you can't outrun your troubles. You have to grab them by their roots. And if she can't dig up the secrets of the Banebury, they might just consume her whole...
