Books in the The Wall series

Cousins Erich and Katarina find that survival in post-World War II Berlin isn't easy, especially when the Russians impose a 24/7 blockade around the city. But everything changes when they sneak inside an American cargo plane and meet a U.S. airman named Fred DeWitt. In the end they must decide: cling to bitterness, or learn to forgive?

Cold War tensions peak and the Berlin Wall traps Sabine and her friend Willi on the wrong side of the city. Though handicapped by childhood polio, Sabine (Erich's younger half-sister) learns to trade weakness for trust when she discovers a forgotten underground bunker.
