Recadat Kongmanee has lost everything to the machines: the woman she loved, the hero's prize she was promised, and her memories. All she has left is vengeance.

Within the Garden of Atonement, artificial intelligences offer healing and a return to innocence. Brought in as an inmate, Recadat must keep up a dangerous charade while she readies a weapon built to destroy AIs-and prove that machines are not gods. But as she's pulled into games of control and obsession, she draws ever closer to forgetting her purpose.

Yet she has not been sent alone, and a hidden ally watches from the shadows to ensure that she carries out her mission . . . or else that she never leaves the Garden alive.
