What The Sea Devil‘s Substitute Is About

The Sea Devil‘s Substitute starts as a familiar werewolf & vampire setup and then quietly raises the stakes every few minutes.

Where it starts: Before the marking ceremony with Alpha Leon, I found out the one he truly loved was my stepsister. He had only been pretending to love me to win the Alpha King election.

The Plot in Three Beats

1. The setup. Before the marking ceremony with Alpha Leon, I found out the one he truly loved was my stepsister. He had only been pretending to love me to win the Alpha King election. In a rage, I drained the entire bottle of wedding wine meant for him. Drunk and foggy, I spent the night with a stranger who broke into the wine cellar.
2. The turn. When I woke the next morning, I thought it had all been a dream. For revenge, I decided to take my stepsister’s place and marry the legendary brutal and ugly "Sea Devil," Alaric. I planned to use his power to become the next female Alpha King. On the wedding day, we switched grooms.
3. The payoff. My stepsister married the highly sought-after Alpha Leon, while I boarded the Pirate King’s warship. I never expected that the handsome stranger who took my virginity was the Sea Devil himself. And I had no idea a new life was already growing inside me.

Why The Sea Devil‘s Substitute Holds Up

• the fated-mate tension charges even the quiet scenes

• Alpha is a lead you will either root for or argue about — both work.
