Consort of Pain by Eva Chase

I’ve overcome the odds to claim my magic and the five men I’m not supposed to love. Then, just when I think we’ve finally found peace, our lives are turned upside down by a life-shattering threat.
If our enemies succeed, we’ll be dead by tomorrow. But they’ve never fought Rose Hallowell before. Even I haven’t discovered the limits of my powers yet. I just wish I could be sure that my magic will be enough. I can’t summon it alone, and the more energy my consorts offer me, the more pain I could cause them.
Can I find new allies to help us win the day—or will we be betrayed all over again?
