Grieving the suicide of a friend, L. Frances Henderson heads to Las Vegas, the suicide capitol of the nation, to seek answers. There she learns about the shocking death of a local teenager who leaped from the roof of the city's tallest casino. While investigating the suicide epidemic further, she finds that the city is also burdened by a national problem scrambling to bury decades of nuclear excess in a nearby mountain. Artfully maneuvering between two stories burgeoning with existential questions, THIS MUCH WE KNOW masterfully links these seemingly disparate subjects of self-annihilation and environmental issues into something supernatural, unforgettable, and transcendent.
