Butterman (Time) Travel, Inc. takes place in the future- in the year 2069 to be exact, when time travel is not only possible, but it has been perfected. The government can time travel and it regulates it strictly. It won't allow private individuals to have their own time travel, but the exception is the 5 or 6 private companies that were able to fund and create their own time travel through their own means, were grandfathered into the system. They are able to continue their time travel businesses but they are HEAVILY regulated by the government. (on a teeny tiny side note, I'm not sure how each of these businesses got their own patents, which means they must have found 5 different ways to time travel, but that is besides the point.) I thought that Butterman (Time) Travel, Inc. was an incredible unique concept, and it was really well executed. I really enjoyed the ride through time that this story took me on. It has been listed as New Adult, but it could completely pass as Young Adult as well. The characters are an appropriate age for either genre and it felt a little tamer than most New Adult books in romantic content. 
 Bianca is the main character. She works for her families time travel company, and she is just one trip away from getting her travelers/ guide license to be able to be a time guide on her own. And the part about being a guide is her induction day. An induction day is so special because it is kind of like a day throughout time where almost anything goes. (the rules all seem to be bent for induction.) I loved learning about what Bianca wanted to do with her Induction day. Bianca is a huge stickler for the rules, and being out in the middle of Alaska means that she pretty much has had no opportunity to get into any kind of trouble. But this all changes when Tristan Helms walks into her business and life. 
 Tristan is a huge pop star, who like so many nowadays, is battling a drug addiction. He has been clean for a few months, but that all gets tested and pushed to the limit throughout their travels. Bianca's parents are going through a government inspection/audit so they are unable to accommodate Tristan, but when he offers them triple their usual rate, they allow Bianca to go with him on her very first trip alone. As you can probably guess they hit all sorts of bumps and roadblocks. But they go on one heck of a journey. I was enjoying the book and then when they leave New York and show up at a huge famous music fest, the book took a turning point for me. It went from enjoyable to super intricate and interesting due to a plot twist. I loved how delicate and complex time travel is. The implications of it seem to be endless, and P.K. Hrezo did such an awesome job playing out different scenarios and ripple effects and they led to some pretty cool plot twists. The second half of this book, I was glued to my seat. I couldn't put it down. This was a great journey. Lot's of fun with a bit of a mystery woven in for the main characters to solve, and of course a great adventure that takes you all throughout time. A really unique read.
