This book requires a slightly different review because, for me, to talk too much about it would be giving it away. Imaginary Girls is the story of two sisters, but it's also more than the story of just them. Chloe and Ruby live in a small town in the Hudson Valley and have been self-reliant for as long as they care to remember. Their mother, whom they call an alcoholic, has been in no position to take care of them and so Ruby ends up being more than just an older sister, she's also a very strong maternal figure to Chloe. Chloe and Ruby have different fathers, with Ruby never knowing hers and with Chloe's giving up custody to her mother. Chloe idolizes Ruby and, in her eyes, Ruby can do no wrong: everyone loves Ruby, goes out of their way to help and please Ruby, and when Ruby wants something she usually gets it. Suma's writing encapsulates their relationship perfectly. One of my favorite things about the book is that it is mostly about 60% prose and 40% dialogue. This might turn people off who are used to having the characters verbally espouse all of the information, but it was used to great effect here. Chloe is used to letting Ruby do most of the talking and generally agrees with whatever decision Ruby makes and so seeing things from Chloe's mental filter only served to enhance the overall story. Let me emphasize that it doesn't remain this way for the entirety of the book and that you will get to see what Chloe thinks of things as events unfold. I have to say that I wasn't a fan of Ruby's character while reading and found her too dominating, but now thinking back upon it - it all worked. Ruby worked. In order for the story to be told and to be as mesmerizing and haunting as it ends up being, Ruby has to be that way. There are a lot of twists and turns that you won't end up expecting and will end up being shocked just as Chloe is at the outcome and what it all means for her and her sister. This is a book that's best left to ruminate in your mind for days after reading as it might not all come together at once, but when it does it's incredibly cohesive and the story one of the most original that I've read in a while.Reading this book in some ways was like home as I'm familiar with all of the places mentioned: having swam in that reservoir and gone shopping at that mall... it made envisioning everything that was happening that much more vivid and real. As a warning, there's no real ending to the book, but don't let that throw you off as the journey there is more than worth it.
