I too feel a big empty space in my life, even though I am so glad to be back with my family. I finished Five Chimneys last night (I slept almost all the way home on Saturday), and like Night, and Survival in Auschwitz, Olga's story is hard to read and hard to put down. I am going to read Salvaged Pages next, on Thomas' recommendation, to try to find some primary texts for my students to read.
Our last evening together, full of singing and laughter, will remain with me always. Check out the U.S. Holocaust Memorial Museum website for updates on Sudan and Darfur. You can sign up for emails that keep you up to date on that and other situations.
