A review by kjcharles
Finders by Eleni Tsami, Melissa Scott

Melissa Scott space opera! A trio of salvage experts who also used to have a poly relationship find themselves at the heart of a storm relating to life-changing nanotech left behind by the Ancestors. This is another book proving the dictum that all current SFF is about climate change: the story is of humanity destroying itself with tech and war not once but twice, and the desperate efforts of thinking people not to do it again. Lots of strangeness and adventure with an intense human heart, and beautifully written.
