So many lives are changed or lost as one by one the ancient bridges fail, succumbing to time and attacks by horrific beasts from inside the trans-dimensional gates. Just one bridge remains—Autumn—and should it fall all connection between the far-flung cities will be lost, sundering families and leaving the populace bereft of resources. Can Julia Destora, a visionary engineer and cool hand with a multi-barrel flechette cannon, rediscover the secret of the gate's geared technology before the final bridge falls? As she helps defend Autumn, the memories of those left behind, her mother's death, and the teeth scars across her own body feed Julia's resolve.
