Tea's gift for death magic means that she is a bone witch, a title that makes her feared and ostracized by her community, but when an older bone witch trains her to become an asha--one who can wield elemental magic--Tea will have to overcome her obstacles and make a powerful choice in the face of danger as dark forces approach.

When Tea accidentally resurrects her brother from the dead, she learns she is different from the other witches in her family. Her gift for necromancy means that she's a bone witch.

Armed with the ability to tame and control the monstrous daeva, Tea enacts her revenge against the royals who wronged her, but she is hampered by her disapproving brother and pursued by enemies wishing to use her dark magic for themselves.

Tea's life, and the fate of the kingdoms, hang in the balance as the Dark grows in her day by day. Tea is a bone witch. Her dark magic can raise the dead, and she has used this magic to breathe life into those she has loved and lost-- and those who would join her army against the deceitful royals. But Tea's quest to conjure a shadowglass, which would grant immortality for the one person she loves most in the world, threatens to consume her heart. When she is left with new blood on her hands, Tea must answer to a power greater than she's ever known. -- adapted from jacket
