I've been wanting to read Free to Fall for ages and I'm so pleased to say it was worth the wait! 
 This book centres around some really high concept stuff but it never feels too overwhelming. It has a lot of things that I generally love to see in books - secret societies, big questions, technology, a super cute romance, secrets - all that fun stuff. Lauren Miller does a fantastic job of writing them around this seriously twisty plot line that left me wowed at the end. The story does take a little while to get fully immersed in but, by the time you do, it's hard to put the book down. 
 Let's talk more about the things I loved, shall we? 
 The technology and its history is so well thought out in Free to Fall. The book isn't set that far into the future (2030 I believe?) and I was happy to see that things hadn't become SUPER HIGH TECH because, honestly, I don't see it happening that soon. The advancements they have in the story are ones I saw as really probable and made it easy to believe were possible. The history of the tech company that's prominent in the story is starting to take off around the time us readers are living in now and it was really cool to see how Miller plays and refers to the tech that we're currently using. For example, North, the love interest who doesn't really buy into the modern technology, uses an iPhone which is practically a relic to them! 
 The characters were another strong point of the book. I was a bit afraid at the beginning that Rory was going to rely so much on Lux, the app that helps users make decisions more easily. Thankfully, she begins to think more about what she's using and the things that are going on around her. I quite enjoyed her narration and watching her develop as a character. North is a boy that I just love. He's a great compliment to Rory and they work fabulously together as a team. He's not too bad boy or too nerdy but a great mix of everything. I would've liked to see some secondary characters more fleshed out, like Hershey, the roommate and Beck, the best friend from back home, but alas, there is only so much that can stuffed into a 500 page book. 
 The concepts in the book give the reader a lot to think about. Things like free will, the extent to how much we rely on technology, and having technology that can essentially make decisions for us. It is made all the more interesting when Milton's Paradise Lost is mixed in. 
 Overall, I had so much fun with this book and love practically everything about it. It takes a bit to get into and it's a long book but it's worth every page for the ride it takes you on.
