She's ice-cold precision. He's stupidly brave and reckless as hell. Their fake marriage might just get them killed... or lead them to love.

Elite Agent de terrain Justine Dupleix has spent five years of training perfecting every detail, following every protocol, and absolutely despising her rival Ash Durham. They've always competed to be the best recruit the Agency has ever produced, and the laid-back New Zealander represents everything she's not: impulsive, irreverent, and impossibly successful at winging it when her careful plans should work better.
Now graduation day has arrived, and their first real mission pairs them as newlyweds aboard the legendary Orient Express.
Their target: a mysterious defector known only as "Bjorn," carrying information that could shift the global balance of power. Their cover: a honeymoon couple on the world's most luxurious train, speeding through Europe's most romantic cities. Their problem: each other.
From the champagne-soaked dining cars to the moonlit corridors, rival operatives from every major intelligence agency have boarded the Express. CIA assassins, German spies, Russian killers, and Chinese agents all want Bjorn—and they'll end anyone who gets in their way.
Trapped together in silk sheets and mortal danger, Justine and Ash must navigate marital bed politics while dodging bullets through Paris, Munich, Vienna, and beyond. He's annoyingly unbothered by her icy fury, treating her death glares like a drinking challenge. Between fake kisses that feel too real and cover stories that cut too close to the truth, the greatest risk isn't the international killers closing in.
It's the way her rival's smile makes her forget every rule she's ever followed.
A glamorous enemies-to-lovers romance where the deadliest secret isn't the one they're chasing—it's the one beating in their hearts.
Perfect for readers who love high-stakes international intrigue, luxury travel porn, and couples who fight as passionately as they fall in love.
