This is the follow-up story to Zinc about three Jewish siblings—John, George, and Eva—who continue to play different roles to help the war effort in WW2.
Will the siblings ever manage to reunite? They share so many memories, but the war keeps them apart.
Based on the extraordinary real-life experiences of Sue Klauber’s father (Coding at Bletchley Park), uncle (SOE in Europe), and aunt (Resistance), Sue wrote Zinc and now Cobalt to illustrate the courage of her Jewish family.
