A marriage forged in battle. Alexei Dvorkin has come a long way since being turned into a metahuman, and all he wants to do is marry the man he loves. A wedding is easy, but it's the honeymoon where his and Sean's past unexpectedly catches up with them. All Sean Delaney wanted was a romantic honeymoon with his new husband. When he and Alexei stumble into a fellow operative's mission on a luxury gambling resort island, they get more than they bargained for in their newly-minted civilian lives. Forced to choose between staying and joining the mission or leaving to stay safe and postpone their honeymoon, Alexei and Sean make the only decision they can-to fight. Fire in the Heart is a companion novella to the Metahuman Files series, an M/M military science fiction fantasy series full of found family themes and spicy romance for fans of Vicious by VE Schwab and Marvel's X-Men and Avengers. It is best enjoyed after New Horizons and before In the Solace.
