Daughters of the Moon: The Sacrifice - Book #5 | 
I always liked Stanton. This one is all from his perspective. Kind of strange not knowing what any of the goddesses are thinking or doing except through his perspective. He briefly becomes mortal through the girls‘ and the goddess of the dark moon‘s help, but then becomes Atrox again knowing that was the only way he could defeat Lambert and save Serena. The ending was super abrupt though. Cassandra is also annoyingly persistent.
