The Doomsday Key by James Rollins

4.0

A Norwegian billionaire and philanthropist is determined to save the earth by decreasing its human biomass. He has resurrected an ancient fungus from the 11th Century that will be genetically modified into all the grains that are being grown around the world. People will starve with food in their bellies. He partners with the Guild to realize his vision. It’s up to Sigma to figure out what he’s up to and find an antidote. To do that they follow a trail through medieval England involving Druids, Celts, and saints to the world’s seed depository on the remote Norwegian island of Svalbard. Lots of action and twisting paths to achieve the end state.
