I loved loved this book! 
 I'm huge fan of historical fiction and WWII books. And to me, The Nightingale is the best one, it's my absolute favorite. So when I read WWIII book, I usually compare it to this one, and I'm usually kind of disappointed because I can never ever feel the same way. But with Salt to the Sea, it was just like with The Nightingale. I loved reading about those characters (which I loved from the first chapters. Except Alfred. I do not like Alfred at all). Salt to the Sea is beautiful, heart-breaking and real. I also really enjoyed reading about a part of history I didn't know. I think it was so important to write this book, and it was so well done. So YES, it's now my favorite WWII book right next to the beauty that is The Nightingale.
