4 stars.
This is the first children's picture book based on the Holocaust and Auschwitz that I've seen and read. To write and illustrate a book such as this for children needs to be done well and right. I believe that given the horrendous and emotional topic, there is a fine line between just how much to mention to such a young audience, but this story was very well told. It focused on the love between the two sisters Rachel and Toby while staying true to the events and cruelty of what it was like inside the camp without overly doing it. At first I will admit I wasn't a fan of the artwork, but by the end of the book, I can see now that it actually fits pretty perfectly with the story. You dont want the whole cute, beautiful and colourful illustrations you see in most childrens books because this story is not your typical childrens book. It is a story of a very dark time and the illustrations show that. Based on a true story, this is defiantly one book I would recommend. I really enjoyed seeing the pictures in the back of the real-life sisters and hearing that they remained so close throughout their lives.
