Bad Blood by Lauren Dane

Trouble never takes a vacation in Bad Blood, the seventh installment in the epic Goddess with a Blade series by bestselling author Lauren Dane.

After spending the last two years locked in one deadly struggle after the next, Rowan Summerwaite deserves delicious meals, excellent sex and uninterrupted sleep on high-quality linens. But when two separate investigations converge in unexpected ways and a new threat to the Treaty blows into town, there’s no rest for the wicked.
And she’ll need help.
Genevieve Aubert, a seven-hundred-year-old witch from a powerful familial line, has become more than a formidable ally. To Rowan, she’s become a friend. To Darius, a Dust Devil from the Trick, where she’s now a priestess, she’s the key to unlocking his magic. The pretty flower to his motorcycles and bruised knuckles.
Soon, the dangerous reality becomes clear. It isn’t just wayward witches. It isn’t just egotistical Vampires. What’s brewing in the desert will take a witch, a Dust Devil and a human vessel to a goddess to save those they’ve sworn to protect.
