Elara Ravenswood never expected much from her marriage to Magnus Thornfield. She knew from their wedding day that his signature on the marriage certificate was nothing more than ink on paper-a business transaction to secure his inheritance from his dying grandfather. But somewhere between the silent dinners and empty bed, Elara dared to hope that perhaps one day, Magnus might see her as more than just a convenient wife.Three years of invisible tears later, everything shatters when Magnus announces he wants to marry Seraphina Blackwater, his childhood sweetheart who's returned from abroad. The Thornfield family rallies behind him, ready to push Elara aside like yesterday's newspaper.But Elara isn't going quietly. She makes Magnus one final proposition: thirty days as a real husband. Thirty days of genuine marriage before she signs the divorce papers and disappears from his life forever. Magnus agrees, thinking it's merely the desperate grasp of a woman with nowhere else to go.Those thirty days become Magnus's undoing. The woman he'd ignored for three years transforms before his eyes-not because she's changed, but because he's finally looking. Every breakfast she makes, every gentle touch, every laugh that fills his empty mansion reveals the treasure he's been too blind to see.When the month ends and Elara walks away without looking back, Magnus discovers that some lessons come too late. The woman who'd loved him unconditionally has vanished into the London fog, leaving behind only her wedding ring and a letter that changes everything he thought he knew about their marriage-and about himself.
