When Shells Crumble - Paperback

The inventor of the Hempattery quits her corporate job to pursue her visionary biotech experiments only to find a back-burnered idea of hers was stolen, bioengineered, and disseminated by mysterious biohackers, leading to a new malleable fungus that takes on properties no one expected. The Robertson family, a sprawling black San Francisco clan, finds itself at the heart of this swirling urban saga. From the 101-year-old matriarch through her youngest son Frank, a UCSF cop, to the urban farming granddaughter Janet, sons and daughters move through this strangely familiar San Francisco.
