Constantine is enraptured by a female for the first time who is under his charge. Ember, princess of the Mer, was to be bred in a rite without her prior knowledge. When Con discovers this, he murders her brother Desmond.

Running from the Warriors of the Mer and desperate to evade capture, Con finds himself hopping from one battle to the next in avoidance and loses an unwilling Ember in the process.

High Demon males also seek fertile females and when an unlikely discovery of a part-demon female falls into their lap, they're not above taking what should not be theirs, even when the consequence is death or worse.

Can Constantine rescue Ember and consume the fire that burns between them? Will the High Demons who seek mates abide by their own laws or sink into the debauchery of lust and power?
