Three Hours Book Review

It’s very hard for a book topic such as this to not have an emotional impact. As a mother of school-age children, I did find myself holding my breath in several parts. It was tense, at times almost unbearably so. I feared for the safety of so many of the characters.
Despite the obvious tension, it was also tender in places and I found it heart wrenching reading about the fear of the children and the bravery of those trying to help. It perfectly displayed people’s capacity for good as well as bad.
There were so many brilliant things about the book but I did find it a bit slow in places. It seems so unlikely considering how tense some scenes were but I felt certain sections dragged on a bit. I predicted some of it which was a bit disappointing, although I admit there’s a lot more to the story than finding the culprit.
There were so many characters and so many different points of view that there wasn’t really time for character development. It was also slightly unrealistic in places and I could really have done without the tenuous links to Macbeth.
Having said that, it did keep me reading until the end and I did want to find out what happened to everyone. The pace picked up towards the end and all loose ends were tied up.
Overall I’d say I liked it, but perhaps not as much as I’d hoped.
