A dangerous truth. A guarded protector. A love she never believed was meant for her.
Lady Arianna Riddle has never been the one people remember. The youngest sister. The practical one. The girl who learned early that quiet was safer than noticed. But when a letter from her late father meant for her late mother lands in her hands, dismissal turns to danger. Someone wants that letter. And they want Arianna silenced.
Christian Ashcombe has learned not to let anyone too close. Working for The Underground has cost him more than most would understand, and trust is a luxury he cannot afford. When he watches Lady Arianna receive a letter at a ball, he knows exactly what it means. And exactly how much danger she is in. He meant to take the letter and disappear. Instead, he takes her.
The dark-haired beauty he noticed from across the ballroom becomes the woman he must keep hidden. But the naive debutante he expected proves to be something else entirely. She is sharp-minded, observant, and the only person who can decipher what her father left behind.
What begins as a mission becomes something far more complicated. For Christian, her mind unlocks clues he has been chasing for years. And for Arianna, he is the first person who needs her for more than her dowry. Somewhere between mistrust and partnership, two people who thought they knew their place in the world discover they were never meant to remain invisible.
But the secret in that letter holds more than answers. It holds the power to destroy the fragile bond neither of them meant to build. And as danger closes in, they must decide whether trust, earned the hard way, is worth the risk.
Lady Arianna's Secret Spy is a sweet, high-stakes Regency romance about finding your courage, earning trust where it was not freely given, and discovering that being truly seen changes everything.
