The plot is crucial. It could be a love story, but add some twists and turns. Maybe the OC has a secret that could either bring them closer to Aro, Caius, and Marcus or drive them apart.

A theme that often appears is the OC's struggle for acceptance in their world. The Volturi (where Aro, Marcus, and Caius belong) have their own rules and ways.
