The Words I Never Wrote by Jane Thynne

In 1936, Cordelia is not happy about sister Irene's wedding to wealthy German industrialist Ernst. Irene and Cordelia were very close growing up on the family's English estate, Birnbaum Park. However, with Irene's move to Berlin, Cordelia worries about the great distance between them and about Irene giving up her painting career. It turns out that Cordelia's fears are not unfounded, as Irene finds herself immersed in the upper echelons of the Nazi party, shocked and appalled about what is going on around her. Cordelia, meanwhile, is living in Paris and working as a journalist. The Words I Never Wrote explores the lives of Cordelia and Irene during World War II and it's aftermath, along with the contemporary story of Juno, who buys Cordelia's old typewriter and finds an unfinished novel in the typewriter case that leads her to want to know more about Cordelia and her life. A great read-alike for Lilac Girls, The Women in the Castle, and Jennifer Robson.
