This book sets the grounds for the following books in the series. A witch owes the head vampires a favour and is obligated to follow through with her word. Problem is that what she ends up doing will give ultimate power to which ever side can tame what she has unknowingly created. A hybrid with the strengths of all the groups but the weaknesses of none. What if this creation became its own distinct super species? The vampires that enlisted her help are hiding a secret that could have them killed and the witch is sitting right in the center of it without knowing.
