I have been enjoying the Shardlake books but have been struggling with the pace of the books to and Heartstone was the worst of them all. I could not manage to read more than 100 pages a day, felt asleep twice with the book and it was just dragging on. I am ashamed to admit I even yelled with happiness when I came to the end of the book.I know this makes the book sound like a bad one but it is not. I just think that reading the 5 books in this series in a row is to much. If I would have mixed them with some faster paced stories I would have probably appreciated this book more. The story is mixed with a lot of historical facts again. Though it takes a while for them to hit up with Shardlake. He is having two missions in this book mixing them up. Both are nice puzzles but one can say two of them is a bit to much. Specially with all the things happening around it. The characters are well set again. The returning characters continue to grow and get more body every book. The two main characters Barak and Shardlake feel like old friends by now. What I did notice more in this book is flaws. I have noticed a bit in previous books but this book has been worse. I though Shardlake had a young boy called Peter and in this book he is called Simon. At some point Barak takes the horses to the soldiers camp while Shardlake is talking to a person still in town and he ends up driving out on the back of a horse somehow. For someone being so accurate with historical details I find it disturbing that the facts of his own story are not always accurate.Therefore three stars for Heartstone. I have been considering 4 stars cause the book is not bad but it frustrated me to much to deserve an extra star.
