I’ve been dying to get my hands on a copy of this book for months and it definitely lived up to the anticipation. Brooks works with the same amount of detail as her book expert, Hanna. The elegant writing paints colorful portraits of each moment in time. Hanna makes a perfect gateway into this world of science and history because you feel as if you have passed her on the street and now you are just seeing the passions of an ordinary woman. At first it seems to be Hanna’s story until you realize that she is just another of the fascinating people of the book. Each character has a fully developed life filled with struggle and the book is just a single chapter of their lives. An absolutely fascinating read that will fill you with every possible emotion.
