I think that it is important to note going in that this is not your typical light summer beach read. But it DOES have amazing characters, a rich storyline, and a gritty, raw and unforgettable writing style. I really like how the characters are authentic and they have problems. They work through their issues in their own ways, but at the end they still aren't perfect. This is not a criticism in any way, but it is a view of real life. The characters do grow and change, but they do not get the happily ever after, even though they learn to be happy with their circumstances. Invincible Summer really has detailed and interesting family dynamics, but I love the message through it all, siblings love and are there for each other. It was touching to see them interact and frustrating when they were being silly. Not silly as in haha but doing real life mistakes and you could see them hurting. I gotta say though, one thing I skipped was all the Camus quotes. I understand that was their thing and what they bonded over, but it's just not my thing. I also appreciate the male POV in this book. I feel like it's well written and true to character. I expected some of the details to be skimped over, but they weren't. Not to the point of gratuity but I got a peek at how guys might think of in certain situations. I could not put this book down, and I'm missing the characters now even as I'm writing about them.
