Mount Dragon.

Mount Dragon is a 1996 techno-thriller novel by Douglas Preston and Lincoln Child. The action primarily follows Guy Carson and Susana Cabeza de Vaca, two researchers employed by the corporation GeneDyne and stationed at the Mount Dragon facility in New Mexico. In attempting to engineer a therapeutic hormone to prevent all forms of influenza, GeneDyne has accidentally created a frighteningly virulent disease. Meanwhile, Carson and Cabeza de Vaca face a much more immediate threat at the Mount Dragon facility—from their own colleagues.
