Book One of the Twin-Bred series asks: can interspecies diplomacy begin in the womb? Humans have lived on Tofarn, planet of creeks and rivers, for seventy years, but they still don't understand the Tofa. The Tofa are an enigma, from their featureless faces to the four arms that sometimes seem to be five. They take arbitrary umbrage at the simplest human activities, while annoying their human neighbors in seemingly pointless ways. The next infuriating, inexplicable incident may explode into war. Scientist Mara Cadell's radical proposal: that host mothers carry fraternal twins, human and Tofa, in the hope that the bond between twins can bridge the gap between species. Mara knows about the bond between twins: her own twin, Levi, died in utero, but she has secretly kept him alive in her mind as companion and collaborator. Perhaps Mara should have expected the enigmatic Tofa to have their own reasons to support her project. Perhaps the ever-cynical Levi should have warned her that members of the human government might use her twins as weapons against the Tofa. Will the Twin-Bred bring peace, war, or something else entirely? This revised edition removes some unnecessary minor character names, relocates a few scenes into more logical places, and divides chapters that lacked focus as originally organized.
