Eclipsed Empire by Tessa Hale

One secret tore my life apart. It sent me running from the place I thought I would be safe, right into the path of untold enemies. But when my life is in danger, the wolves I thought I'd lost for good are the ones who come for me. And they'll burn down the world to keep me safe-even if none of us trusts each other anymore. With every moment we're forced together, every whispered apology and stolen touch, my resolve to keep them at a distance weakens. And when I realize just how much each of these men has come to mean to me, that resolve crumbles to dust. Only there are more secrets to uncover-all our pasts lurking in the shadows. And when the monsters emerge from the darkness, there's no escaping them this time…
