It isn't often that I write a review. On average, I read 3-4 books a week and it's even less often that I find a book worth a review. But after finishing The Sea of Tranquility, there was no question in my mind that I would take the time to sit down and write my thoughts. 
 1.) The character development was phenomenal; I was concerned for them, embarrassed with them, laughing and crying at all the moments that they laughed and cried. And that goes for all of the characters, not just the MC's. Somewhere along the way, they became real. I talked about them with my husband as if I had sat down at lunch with them that day. They found their way into my heart and mind, and when it was over, I missed them. I wondered what would happen to them and I knew I would never, ever, forget them. 
 2.) The story line flowed smoothly and kept you wondering what was going on without feeling lost. Katja was able to give just enough to keep your attention and more than enough to keep you reading. It was unpredictable and frightening because it kept you wondering when everything would go to hell. And when it does, well, hell was raw and heartbreaking and oh so necessary. 
 3.) I felt as though the trials in the book were dealt with adequately. The emotional responses to every situation were realistic and heartfelt without being overly dramatic and annoying. Katja took her time, let the character's come to conclusions that had you screaming YES! instead of yelling what you would have done instead. 
 It's been a week since I've finished it, and I still think about how it made me feel. The emotions it evoked aren't comparable to any other book, and for that alone it is worth more than it's price. Read this book, you will not be disappointed!
