BookNook — Young Adult book reviewsLet me paint a picture for you. You're crying yourself to sleep at night because you just finished reading Pivot Point and you're afraid that nothing will ever live up to the awesomeness that is that book. Well, allow me to introduce PARALLEL! This book is the perfect follow-up to Pivot Point; they're very similar in nature, but also vastly different. And I promise you that Parallel will rock your universe (the parallel ones too!).Parallel is so much more rooted in science than I ever imagined. I have no idea how much the science aspects of Parallel are actually connected to real scientific theories/speculation, but I don't care, because Lauren Miller makes it sound 100% believable. This book isn't just about the fantastical idea of parallel universes. Lauren Miller creates an entire scientific reason behind them. You won't sit there thinking, "Oh, what a cool fantasy idea!" Instead, you will imagine this actually happening happening in the world! It's both fascinating and terrifying at the same time.LIfe can only be understood backwards; but it must be lived forwards.At first, Parallel might be a bit of a mindfuck. I had to re-read the parallel world explanation like 3 times before I finally got it. Basically, there are two parallel worlds, but they're not running at the same time. One (the 'main' one) takes place in 2009, and the other one takes place exactly a year earlier in 2008. When the Abby in the earlier parallel world makes course-altering decisions, they affect the other Abby a year later. So you can see how teeny tiny decisions, choices, lies, exaggerations of the truth, and mistakes affect Abby's path and course of life an entire year later. It's absolutely insane to see how such tiny things can have such huge impacts in the long run!Abby basically has no control over her life because the decisions that her parallel makes ultimately affect where she ends up. For example, maybe in the 'normal' world, Abby is currently in university. In the 'earlier' parallel world, Abby is still in high school. But maybe, today, the earlier Abby drops out of high school for whatever reason. Then, when the 'normal' Abby wakes up tomorrow, she will no longer be at university because the decisions the 'earlier' Abby made suddenly set the 'normal' Abby on a different path. I know, it's a little confusing at first, but when it makes sense (which it will as you read the book, I promise!) it becomes this huge fantastical scientifical web of awesomeness.Who knew fate was so fragile?Parallel deals with a lot of ideas like fate and destiny. Because of the nature of the book, the 'normal' Abby feels powerless. It's as if the 'earlier' parallel Abby is controlling everything, and the 'normal' Abby has no say! This raises a lot of questions like: can we control our destiny? Are our lives predetermined? These questions are addressed by an awesome scientist character, Dr. Mann. He's a really interesting character, because he's a scientist who has written theories about parallel worlds and how they might collide.The characters in Parallel are just as awesome as the plot! You will love every single one of them for different reasons. Abby is a perfect main character. She's interesting, she's smart, but sometimes she does make stupid decisions, and you can see how those decisions affect her long-term. And I LOVE her best friend Caitlin! Caitlin is a total science nerd, but she's also awesome, gorgeous, and an amazing best friend! I love her relationship with Abby and it completely broke my heart when they had a fight about halfway through. I don't think I'd ever actually cried over a best friend type relationship before reading Parallel, but that moment actually got me teary-eyed!We're all just a decision or two away from destroying the relationships that are most important to us and to the people we love. And most of the time, we never even know it.Even the side characters are amazing and hilarious. This one—Fiona—is only in the book for like two seconds, but I don't care, because she's amazing."Fiona!" a male voice calls. A hulk of a guy in a shirt that could double as a bedsheet is waving from across the courtyard. His forearm is the size of my thigh."Be right there!" Fiona sh outs. "My boyfriend," she explains. "And yes, the size thing is an issue in bed. I once tried to straddle him and pulled my hamstring.There is a romance in Parallel and it's actually quite similar to Pivot Point in its approach. There are two different love interests: one for each parallel world. So yes, there is a bit of a love triangle, but it's so interesting how it's done! We have Josh in the 'earlier' parallel world, and Michael in the 'normal' world. At first, I actually wasn't crazy about either of the guys. I think I felt the same way about Michael that Abby's parents do. If you asked me to describe him, I'd use words like "Confident". And I don't mean that in the best way. He's so confident that he comes off as cocky. He's also just not my type at all. He's a party guy, a little closed off, and I just didn't click with him. And then there's Josh. I thought Josh was a little too corny for me, and for the longest time I had no idea where their relationship was going, if anywhere. But by the end of the book, Josh definitely did grow on me!"I invited Josh to go with us Ilana's party.""Who's Josh?""Josh Wagner. Astronomy Boy.""You invited Astronomy Boy to go with us to a party we're not actually attending. Interesting strategy. Shall I bring the boyfriend I don't actually have?"To be honest, I'm not completely sure how I feel about the end of the book. I loved it, up until the very last second. It's still good, but it almost had me wanting more! Josh and Abby make up and finally get together! I loved how that turned out and I was so happy that she chose him! But then the worlds like.. un-collide, and Abby and Josh have to basically start over from scratch because they don't even know each other yet. And then it ends. I guess the ending totally does make sense, because the worlds un-colliding will allow Abby to finally live independently. And it is definitely implied that Abby starts pursuing Josh.. but the fact that we don't actually see that happening left me a little unsatisfied!Ultimately, this is a fabulous book. It's hilarious, it's fun, and it's so freaking interesting. The ideas in this book and the way they are presented are genius! This book is so carefully crafted and I loved seeing how tiny things can have huge ripples in Abby's life. I can't recommend this book enough!
