Two people. An impossible task. A traitor in their midst.

Sofi’s mother desperately needs medicine, and Sofi will do anything to get it—including a one-month stay at the Brunberg mansion in Helsinki, the capital. There she’ll spend her days at the Kangas Tailor Shop, knitting silk stockings and other items from sunup to sundown for the biggest wedding of the decade. If she can do it, Sofi will have the ability to get the medicine her mother needs, with money to spare.

But Sofi’s safe world of knitting needles and thread is turned upside down when she finds herself in the middle of political intrigue. Antti, tailor and owner of the shop, Sofi uncover a plot to sabotage the Brunberg daughter’s wedding and threaten to bring Russia’s fist onto the Grand Duchy, removing the Finns’ self-governance, and possibly lead the countries into war.

As Sofi and Antti work together to save their country, she can’t help falling in love with the unassuming and attractive head tailor, though she knows she can’t have him. Her country and her family need her, and when her job is done, she’ll go home to Porvoo, never to see him again.

As they race to stop the traitor, the battle in her heart intensifies, and she fears that the victor won’t be love.
