Shadow Matter — S.W. Mayse

A future recasting of the Orpheus and Eurydike myth that weaves together love, loyalty and the restorative power of art. The war is lost. Seren Qasri is on her way home, her memories of the final days of the war a disturbing blur. Her occupied homeworld of Claer is in ruins, her mother is missing, and her lost love Teak Kuhan survives only as an avatar. All Seren knows for certain is that she must report in with her data—information that could force a renegotiation of the peace treaty and free her homeworld. But Seren's commanding officers aren't the only ones who want that data or knowledge of the events buried in her memory. Pursued by ruthless killers, Seren doesn't know who she can trust. As her memories of a diplomatic courier's murder return in fragments, Seren strikes a truce with Tas Damou, the freelance who once betrayed her. They detest each other, but only Damou can help Seren stay alive long enough to carry out her task … and prevent another war from engulfing human space.
