Carpe Diem

Josephine Wren Hawthorne has spent her entire life at the New York Institute, raised alongside Alec and Isabelle Lightwood and the boy who would become the most reckless Shadowhunter she knows-Jace Wayland.
To the outside world, they are elite warriors of the Clave.
To each other, they are family.
Josephine is the steady one. The protector. The person who holds the group together when missions go wrong and emotions run high. She understands Jace in ways few people do, and somewhere between childhood training sessions and dangerous demon hunts, their friendship grew into something more.
But everything changes the night a mundane girl stumbles into the Shadow World.
