My best friend is still missing, time's running out, and I'm all out of ideas... My five guys and I travelled to Europe to rescue Zoe from her dragon kidnappers, but my newly developed powers are failing me. Instead of pinpointing her location, the most I can manage is a little static and a lot of frustration. When we team up with a group of local rebels, we learn more about our common enemies—including exactly how dangerous they are. An unexpected attack also proves they're always one step ahead of us. Only the strengthening bond my boys and I share seems to be going right—until an unthinkable betrayal threatens us all. The Fire of the Dragon's Heart is the fourth book in the Harem of Fire series, a medium-burn reverse harem fantasy romance featuring five dead-sexy dragon shifters and one sassy human heroine with a propensity for finding trouble.
