A Night Divided

Jennifer Nielsen is one of my new favorite authors.  She wrote The False Prince and its two sequels in the Ascendence Trilogy.  Like those, this is a historical fiction novel.  This is set during the Cold War in Berlin, right after the wall went up to separate the democratic sections of the city from the communist.  Gerta's father was on the other side of the wall when it went up overnight.  For four years the family was separated until she sees him one day on the other side.  His strange dance motions are sending her a message.  When she figures it out, she must use all her courage to do what he is asking and try to reunite their family.  (FIC NIE)
