The biologist on a subterranean mission

Ann Cheeptham is a cave-exploring micro-biologist on a mission to find a solution to one of the biggest threats facing the global population today, our growing resistance to antibiotics. She's hunting for bacteria that could form the basis of new, more effective antibiotics, a search that's taken her deep underground.
