Princes of Hell by Sara Humphreys
When Kai Kelly inherits her estranged grandfather’s estate in Bliss, Idaho, life becomes anything but blissful. The discovery of a beautiful, but unusual, ring in the attic leads to much more than she bargained for. Kai may not realize what she has in her possession, but the boys in Hell sure got the message. Lucifer and the six other princes of Hell existed for several millenniums believing that the Ring of Solomon, an object with the power to control demons, had been destroyed. However, the moment Kai slips the ring on her finger, the tremor of its power ripples through the underworld. Knowing the ring’s existence could mean the destruction of all demons, Lucifer sends his six brothers to human realm in search of the ring and its bearer. There’s one catch; a demon can’t take the ring from its owner. It must be given willingly or they have to be dead. Asmodeus, the Demon of Lust, is happy to have another opportunity to visit the mortal world and dally with a human female…or twelve. When he encounters Kai along a deserted section of highway in Magic Valley, it’s more than the ring she wears that catches his eye. He plans to woo the ring out from under her but before long, the lines between lust and love blur. The Brotherhood is determined to get the ring from Kai at any cost. Asmodeus must choose between the Brotherhood and his one true love. The battle for Hell is nothing compared to the battle for her heart.
