similar to Oryx and Crake, again we jump back and forth, before and after the plague 
 this time from the point of view of members of a quasi religious, vegetarian, survivalist cult, the Gardeners. 
 we follow several members who drift in and out of the cult, (view spoiler)[most of whom survive the plague (hide spoiler)] 
 the genetic engineering and the machinations of the corporate / security complex are less defined here, rumours swirl. 
 appears to take an anti-science slant, the coming waterless flood will be a cleansing for the Earth
