Seraphina thought she was a typical twenty-one-year-old college student who loved getting sugary mochas with her best friend, Victoria Sharma, and practicing ballet. Her plans for after college were soon derailed when she encountered the enigmatic and devastatingly handsome Gideon. Her adopted mother, Celeste Chevalier, claimed he was a co-worker of her homicide detective boyfriend, Jebediah Silver Feathers. Seraphina's immediate attraction to Gideon was undeniable. Still, she didn't know he was the Lord of the Powers, a warrior class of angels. Assigned by the Council of Archangels as her Guardian, he had been watching her all her life. Unbeknownst to her, Gideon was also the Guardian of her father, Zanael, the first created immortal Earth angel that died. One of the mind-blowing bombshell secrets of all was that her adopted mother and her boyfriend were not who they seemed.
Seraphina's life took a dramatic turn when she was thrust into a supernatural realm of celestial angels, fae, immortal High Witches, and demons. As dark forces of rogue angels and demons closed in on her, she discovered her true identity as a half-angel/Nephilim, concealed as a human. She was the bearer of the mystical blood seal of the seven Archangels, a legacy passed down from her father, Zanael, the first immortal Earth angel. Gideon, her Guardian, had the daunting task of training and protecting her; he was supposed to be her father/uncle figure. But he cannot deny his growing attraction for her. Their forbidden romance will challenge the supernatural community's rules as dark forces threaten to turn their world upside down.
