All the Little Hedgehogs

In Soviet Union, genetic engineering does you. Yona wondered why everyone kept steering him toward a military career, until one of his teachers noticed his aptitude for genetics. Now he's the personal student of Academician Voronsky, working in a secret genetic engineering facility in a closed town. However, Yona keeps having to spend as much time babysitting the Academician's adopted son Kolya as actually doing genetics.
When this extra assignment becomes a frustration, Yona learns just how quickly privileges can be retracted. And then he starts learning just how deep the secrets of the Soviet human genetics program really goes. A story from the Grissom timeline (Gus on the Moon universe).
