The Crux Ansata, known to some as the tools of the angels and to others as ankhs, are the keys to supernatural abilities that empower the guardians to manipulate earth, air, water, and fire. The story unfolds as four young men deal with the challenges of young adulthood, fraternity, and friendship while facing angels, demons, local authorities, a crazed serial killer, and a secret brotherhood that has been searching for the Crux Ansata since the beginning of time.
