I usually have more than one book going at a time, so here's what I'm reading now:
The Secret Keeper by Kate Morton. I love Morton's writing - it's so lush and lyrical. She pulls you into the story and creates an incredible world.
A Woman in Berlin by Anonymous. This is the second time I've read this book, but it's for research. It's about a woman who was in Berlin during the last days of the Third Reich, and what she saw and endured when the Russians came.
With the Old Breed by Eugene Sledge. This is the definitive memoir of the Pacific War as told by Sledge. It's brutal and gripping. The HBO miniseries, The Pacific, took a lot of its content from this book. Again, this is for research, but it's a book that every World War 2 historian should read.
