Involuntary Reroute is an in-depth look into the history of a travel-hacker. You get the twists and turns of the author's life as he worked to stay ahead of the companies. You get a good idea of the thoughts going into each decision and the repercussions that come along with sharing the loopholes they find. They created such a buzz within the travel community that they drew the attention (and ire) of multiple large companies, but through the advice of those they partnered with along the way, they were able to settle the score.
This was a fun read. I was interested in each twist and anticipate the next book in the series to learn more about the involuntary reroute leading him to his next adventure in travelling!
