e, set in and around Washington, D.C. Newly minted engineering professor Jake Harper, dealing with issues of mild dyslexia and awkwardness with public speaking, wants to stave off climate weirding by re-engineering the North American electric grids. His pregnant partner Abbey London, sassy but irresistible, starts her practice as an infectious disease specialist, concerned with encroaching tropical diseases. Together they operate her parents' Dragonfly Inn just twenty minutes away in northern Virginia.

A chance encounter at a lecture at George Washington University causes Jake to become suspicious that someone may be plotting a cyberattack on critical electrical infrastructure.

Abbey discovers an infection new to North America has infiltrated the drug-injecting population in the Capital, and she must personally and professionally rise to the challenge.
