A time traveler! So fun! This is a cool idea for a book. I especially liked that the author cites future philosophers and future theories because it made the creation of her future more credible and thoughtful.
My one beef (*spoilers*): There is this big reveal at the very end when the time traveler - Ridge Sabio - gets back to his time in the future after visiting the thrilling year of 1999 and he reveals that he met Elizabeth Gibson and his whole family (of time travel scientist geniuses) freaks out and asks him all these questions about her and I was like, wait, who the poop is Elizabeth Gibson? So I RE-READ the entire book to figure out where she was mentioned because she was clearly someone important and I had obviously missed it and discover that she HADN'T been mentioned anywhere in the book. ?? And then I proceed to read the epilogue or post-book-notes or whatever you want to call them and THAT is where you discover who she is. Personally, I think it would have been cooler if the author had made a bigger deal about The Founder (always un-named) during the book because I apparently completely skipped over the two fairly insignificant references to her and therefore had no idea what the Sabios were talking about at the end. BUT the reveal was still very cool and perhaps the author really did want us to be super confused and re-read the book to try to figure out the connection. *shrug*
