Oh boy. I hate giving bad reviews but I can't give a completely good one for this book.
While I think Claire Tomalin can be a good writer and she definitely did a ton of research, there is just not enough Jane in this book.
I assume after reading this that we don't know too much about Jane. We don't even really know what she looks like as there are so many different descriptions of her and this one picture drawn by her sister was apparently not accurate, and yet we use it to depict her.
The book was pretty long and most of the info in it was about Jane's relatives or neighbors.
While it did have some very interesting information in it, I just found it slightly tedious and I really feel like it could have been half as long and there were a lot of things that could have been left out, especially speculation.
