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.

When Lara Williams gets a job aboard the luxury train the Banebury for her gap year, she thinks she’s landed a five-star escape from her past. Even after she learns that her ex-friend, Rhys, who she definitely did not have feelings for before their relationship imploded, is one of her coworkers, she’s determined to make things work.

But on the first night of their journey, the trip takes a strange turn when two mysterious carriages, filled with an array of beautiful and rare plants, are attached to the Banebury in the middle of the night.

With them come a pair of siblings. Wealthy, Welsh, and alluring, Gwen and Gwydion claim the plants they’re transporting are for research, but Lara can’t shake the feeling that there’s something . . . otherworldly about the strange blooms. Something that wants to ensure the Banebury never reaches its destination.

Soon Lara will learn: You can’t outrun your troubles. You have to grab them by their roots. And if she can’t unearth the secrets of the Banebury, they might drag her down for good. . . .
