nds with her former friend group takes a sinister turn during a weekend getaway at an ancestral Irish estate in this atmospheric, literary horror from the author of Those We Drown.

There's something in the lake at Wren Hall.

At least, that's what the locals say. Not that Meg cares much about the rumors. When she's asked to spend Halloween weekend at the Ireland retreat of the wealthy Wren twins, she recognizes the invitation for exactly what it is: her last, and only, chance to save her spot at Greyscott's, the exclusive British art school she attended on scholarship until last summer. Clever, beautiful, and talented, the twins are the pride of Greyscott's, and kindhearted Lottie Wren was once Meg's closest friend. But not anymore.

None of Meg's old friend group have talked to her since she left school--and they especially don't talk about the incident that resulted in her suspension. Now, Meg is willing to do whatever it takes to earn their forgiveness.

But Wren Hall turns out to be far from the idyllic country manor Meg was expecting. The house is damp and drafty, the mirrors are all covered, and the weed-choked lake is at the center of legends that haunt the property to this day--a tainted legacy the estate seems unable to shake.

The truth is, people aren't the only ones who keep secrets. Places can keep them too--and Wren Hall is drowning in them. When the past bleeds into the present and ancient sins rise to the surface, Meg must ask herself how well she really knows her one-time best friends...or whether any of them will survive the weekend.
