Mars. 2368. Eva Aucoin, sheriff, is already six bodies and zero clues into a murder investigation when the post-human Authority sends one of its agents in search of answers. With the colony's inhabitants in more danger than they ever were from a single murderer, Eva quickly realises she and Authority may be looking for answers to very different questions.

Civil war took them to the edge, to the decimation of their society and the destruction of their entire way of life. Now, ten thousand years after their abilities almost destroyed them, one Caucker must risk unleashing the past to secure the future, not only for Cauckers, but for all of humanity's children spread across the galaxy.
