From the critically acclaimed author of Bunny comes a horror-tinted, gothic fairy tale about a lonely dress shop clerk whose mother’s unexpected death sends her down a treacherous path in pursuit of youth and beauty.

Can she escape her mother’s fate—and find a connection that is more than skin deep?

For as long as she can remember, Belle has been insidiously obsessed with her skin and skincare videos. When her estranged mother Noelle mysteriously dies, Belle finds herself back in Southern California, dealing with her mother’s considerable debts and grappling with lingering questions about her death.

The stakes escalate when a strange woman in red appears at the funeral, offering a tantalizing clue about her mother’s demise, followed by a cryptic video about a transformative spa experience. With the help of a pair of red shoes, Belle is lured into the barbed embrace of La Maison de Méduse, the same lavish, culty spa to which her mother was devoted.

There, Belle discovers the frightening secret behind her (and her mother’s) obsession with the mirror—and the great shimmering depths (and demons) that lurk on the other side of the glass.
