March, 1935. Everything about sixteen-year-old Popi Kapsulis's life has changed thanks to the rumors of another Great War on the horizon. The Italian Forces have already closed the schools and churches on Popi's small Greek island of Kalymnos, forced her people to learn Italian, and are now burning businesses to the ground-all in an effort to rebuild the island they've come to occupy. Life has become unbearable and Popi can only think of one thing: freedom.

When Popi joins the Resistance, she rallies other island girls and forms a secret knitting society. Her plan is simple: she and the other girls will spy on the Italian troops and knit the intel into doilies using Morse code. The doilies will then be passed on to the Resistance to decode and take action. Her plan has the power to change the course of history, and as Popi's espionage starts making a difference, freedom feels within her grasp.

Until she meets Emmanuel. Falling in love with the enemy was not part of her plan. Neither was getting caught. Before Popi knows it, everything she loves-her family, her friends, her life, and the freedom she has fought so hard for-is suddenly hanging by a thread.
