By Means of Clockwork Selection
Connie survived the plague that devastated plants, animals and clockwork alike. Her life has settled into the relative peace of farming clockwork ponies and marriage to her childhood sweetheart, Bess. But the threat of plague is never far away. Mutated oaks are spreading over the ruins of London and stories of outbreaks abound. She fears the worst when a pony collapses, but the true cause is far more surprising. It might be the key to rebuilding the world. (A novelette.)
