There are aspects of this book that I enjoyed and just as much that I didn’t enjoy. The writing is good without multiple grammatical issues which is a huge plus in my book. That said, the writing didn’t help with connections and at times made me want to either skip to the next chapter or pick a different book to read. Having raised two teenagers of my own and worked with troubled teens I found the constant negativity from Miles to be over the top. This negativity began to grate on my nerves about half way through the read. Parts of the book felt well thought through, even well researched, while other parts felt as though they were lacking any solid foundation. This is especially noticeable when referencing dated aspects, with some dating issues being more obvious to me and pulling me out of the read. I have mixed feelings about the science fiction explanations for time travel and how it supposedly would work. I don’t feel this will be a huge deterrent for YA readers, however I wouldn’t recommend this to YA readers due to the language usage by Miles. I don’t believe foul language does anything to add to a book and I certainly wouldn’t want my son reading this. Overall the plot is intriguing and with some minor fixes would fit well among other YA books. I received an ARC in exchange for an honest review. This in no way influenced my opinion.
