Garrett Primross is the sole survivor of an epidemic that killed the woman he loved. Garrett knew Dinni was not his HeartMate but his love overrode all desire for any other woman.

The Iasc illness has reappeared and the Healers are asking for his help. They want to infect him again and observe him during the illness. Second level healer Artemisia Panax will be the observer. Only Garrett knows that Artemisia is his HeartMate.

After Garrett's recovery, he is asked to lead the investigation into a murder. The victim was a man who was a murderer himself. His murders were religious in nature. Everyone connected with that religion was investigated and many were disgraced. Artemisia's family were members and the disgrace drove them out of their home. The investigation will bring them closer together.

Ms. Owens has continued her highly successful Celta novels with this latest entry. A highly complicated story with the intertwining of the two parts of the story, HEART SECRET will keep readers engrossed as they unravel the mysteries in the story. I love this series and hope she can continue with this series for a long time.
