Derivation. Aberrant Magic, #2

Darren and Kavon have committed to each other, but magical rules are changing and that tests the strength of their bond. The death of a prominent Egyptian shaman and the shadowy remains of O'Brien's conspiracy to kill adepts and steal their magic also pressure the new couple. Kavon is determined to protect his partner through these storms, but he is also painfully aware of his own tendency to hover.
And as Darren is quick to point out, he is an armed federal agent who won't allow Kavon to keep him off the front lines. Making the relationship even more difficult, the spirit guides who offered their loyalty have their own hopes and needs. The world is changing, and Darren's spirit guide pushes them to find the right path to navigate. However, Kavon has never enjoyed being pressured, and he is particularly uncomfortable walking into a situation he doesn't understand.
Worse, the longer he knows Darren and his guide, the more confused Kavon becomes about how magic even works. The two men must pull together or the forces moving in the shadows threaten to destroy them before they have any chance at happiness.
