After his long and arduous chase brought Isidor time and again inches from his quarry - the mysterious Darcy, the "Heart Thief" - he found the tables turned on him, prisoner to the thief themself!

The enigmatic serval is full of surprises, not least of which is that, much to Isidor's distress, he rather enjoys their company. The thief seems equally flummoxed by their growing bond, but who can say what lies in their heart or motivates their decisions? Every new piece of information is cryptic, every feeling Isidor grapples with excruciatingly confusing. This only worsens the more Isidor learns about the conspiracy at the heart of the crime he has been attempting to solve.

The Ministry of Templar has finally begun to take interest in his investigation now that the noose is tightening. Isidor is forced into an unenviable position: maintain his role as a Templar while hiding what he knows, including potentially protecting Darcy from his very own Brothers-in-arms. The line between enemy and ally begins to blur, and where Church and State secrets are concerned, the penalty for betrayal can be blood.

It is hard to hold the heart of another in your hand under the best of circumstances. It is far harder when the world around you will not even recognize your love as real.
