These Mortal Bodies - Elspeth Wilson

Ivy Graveson didn’t grow up in their world, but she’s ready to do whatever it takes to become part of it.
 
Leaving her quiet coastal upbringing behind, Ivy arrives at an elite all-girls college and dives headfirst into university life. Surrounded by students who seem effortlessly wealthy, connected, and confident, she refuses to remain the outsider.
Drawn into the allure of secret societies and old college traditions, Ivy begins to uncover unsettling ties between the institution’s shadowy history and her own. No matter how hard she tries to shake it, she has always felt both compelled by, and afraid of, the deep waters that have shaped her life.
 
Over the course of a single transformative year, Ivy must learn what sisterhood truly demands and decide just how far she’s willing to go to become the version of herself she’s always sensed waiting beneath the surface.
