Downloading In Iron Stars (The Ancients’ Bargain 2)
Sirens have a biological imperative to empathically bond with their partner. It's supposed to be a soft melding of nervous systems, intertwining two people as one, but people like Saoirse, a khavira, have a genetic defect that make that bond fatal to their partners. Love just isn't possible for her. She accepted that a long time ago, distracting herself with her work as an Inquisitor. So she's a bit at a loss of what to do when her boss tells her she'll be escorting her ex to a research station through uninhabited mountains. It takes over a month roundtrip. That's over a month with Iza, the woman who once was Saoirse's entire world.
And perhaps worse yet, Iza's going with her husband.
