The Devil's Set is hunting for the greatest treasure of their lives--this time in the wilderness of Yellowstone National Park. With so much on the line, can Xavier Price unlock Rinaldi's latest set of clues while battling his hot, not-so-convenient feelings for The One That Got Away?

Park ranger Penny Vaughn has spent the last few years trying to get over her brief, fiery marriage to Xavier. When he and his “business partners” show up at Yellowstone seeking her help, her first instinct is to run like hell. But then her curiosity gets the better of her, and soon she’s swept up in a thrilling adventure with the man she swore she would never forgive.

As they face the dangers of the wilderness together, Xavier and Penny quickly learn that the heat they shared years ago still burns wild and hot. But can they see beyond the pains of the past to give themselves a second chance at love?

PROTECTING HIS PRIZE is Book 3 in the gripping Devil's Set series by USA Today bestseller Ember Casey.
