Burning Bridges by Laura Anne Gilman

Rediscover the world of the Retrievers and the Cosa Nostradamus, in book 4 of the popular series by Laura Anne Gilman.

Wren Valere used to be almost invisible. But now she's not only being seen, she's getting involved.

Recent attacks against nonhuman Fatae have escalated into hate crimes against magic users in general – humans included. With the Mage Council distracted by internal power struggles, Wren is guilted into stepping up as spokesperson for the fragilely united Fatae and lonejack communities….

And, because the cosmos deems her without enough complications, her partner–lover Sergei is drowning in his own problems. But not only can't she help him – she's the cause.

With lives on the line – including her own – Wren is going to have to break the lonejack credo, ditch her long–cherished invisibility and take a stand.

But burning bridges can be deadly….
