What an enjoyable book! It took me back to my days of reading the Choose Your Own Adventure books for hours.
I really like the writing style and the book is funny as well as fun. I was surprised in how many different directions the story split into and in a true time-travel, "you can meet yourself from different times" form, you get to cross some of the other madcap adventures in the book that I thought had nothing to do with the main story. Lots of cool references to other time travelers and pop culture through-out.
Well worth it! Now to get the other books. Or maybe a future me went back in time, bought the books already and they are waiting in my downloads. :)
