I read a lot and it takes a lot to hold my interest for over 500 pages. This book did it in spades. Of course, historical fiction is one of my favorites. Throw in a mystery, a myriad of characters over a span of 200 years and you have a mix that's hard to beat in my opinion. I recommend this book for anyone who enjoys historical fiction and who has ever even visited Boston. I was sorry to see it end.
