First volume of the "Organic Future" series. The genetic engineers aren't about to stop with genetically modified food. It won't be long before they're playing with houses and vehicles too, and someone is trying to kill gengineer Emily Gilman! The Chickadee at the bird feeder is the size of a Piper Cub, a Sparrow airliner is gobbling Buggies on the highway, a Mack truck is lunging across the sidewalk, and detective Bernie Fischer is flying his modified Sparrowhawk to the rescue.
