When Astaria discovers the secrets of the letters her mother has long locked away, her world shatters. She is taken to the Diamond Halls, where her stepfather works at the President's Chief of Security, to be locked away, a prisoner of society in a cold diamond castle.

Until the day she escapes, leaving behind her icy mother, her beloved brother, and the sister with a secret. But what she finds, as she draws her sword in the forest of glass, is not quite what she expected...

Obsidian, were-lion, pack leader, and street fighter. Echo, the boy with mysteries in his dark eyes, Astaria's protector that steals her heart and nearly leads her to her death. Remthin, blind, left on the streets by his parents when they discovered his crushing power over time. Syra, a dark-haired beauty who can burst into white-hot flame.

With them, she finds adventure, danger, love and a sense of belonging
