Time Riders by Alex Scarrow Review

This is a good rainy day read. A bit slow to start, but once the story got going it was pretty good. I enjoyed the concept of the story line, an unknown agency who calls themselves "Time Riders" travels through time to protect history. The only time machine made was destroyed by the inventor because he did not want anyone to be able to alter "time". But did he really destroy it? Why would there be an agency to protect history if the only known time machine was destroyed? Not enough to get you to want to read the book yet? Well then add people from the future who travel back to Hitler to take over the world. That could end badly.
