His Daughter Consumed The Truth

Jessica Carter has lived for thirteen years without a mother. As a freelance journalist and writer, her mother spent years uncovering the misdeeds of the rich, the corrupt, and the evil people of the world... and the serial killer ‘Samael’ murdered them. When Jessica lost her mother, the killings stopped and Samael disappeared.

Three months ago, an organization of Samael’s followers emerged, intending to kidnap Jessica for reasons she still cannot understand. Now, with the help of her friends, the returned Corinne Masterson and FBI agent Erin Finch, Jessica is coming out of hiding to finally put an end to Samael and his cult.
...
And four years from now, Ashley Goodwell finds herself mysteriously freed from prison. Promised the chance to receive a pardon if she can stop her nemesis from joining Samael, Ashley would do anything if it means seeing her son again. But a question lingers in the back of her mind: what happened four years ago that prevented Jessica from fulfilling her mission and ending Samael once and for all?
