booknook — Young Adult book reviewsKatya's World is like no other book I've read! Maybe it's because I don't read a lot of hardcore science fiction, or maybe it is because this book is just so unique, but either way, this story and world was completely new to me. This book is heavily rooted in submarines, crafts, technology, and navigation. But don't freak out! It's not so heavy that it's difficult to follow. It was definitely piled on more than other books I've read, but I wasn't overly intimidated or confused by all the technology and submarine lingo! In fact, it was really interesting to read about, and I'm a pretty big noob when it comes to that stuff.Katya was an absolutely brilliant character! She's exactly the kind of main character I like to read about. She's quite young (15), but she doesn't act it at all. Since life is so hard on Russalka, most childhoods are quite short. But even so, Katya is referred to as being really intelligent—even by Russalka standards. I just love it when there's a smart, young main character who waltzes in and kicks ass. Katya doesn't kick much ass physically but her intelligence certainly does the job for her! I loved watching her outsmart older industry officials, but still not have an annoying arrogant overtone.This book is filled with many other awesome characters. They're all so different and well developed, that it's hard to even list them all! After Katya, Tasya is my favourite character. She's a fierce, deadly pirate whose reputation is enough to scare away any fed. She's in charge and she'll kick your ass.. physically. 'Nuff said.Katya's World has so many different sides to it. On the one hand, we get the history of Russalka, its colonization, and its war with Earth. It's a really engaging and intriguing back story. On the other hand, we get Katya's coming of age story. At the beginning of the book, she has just earned the card that declares her an adult. But by the end of the book, she has gained the real life experience and knowledge to really prove that she's worthy of the card. And on the other hand, we get an absolutely insane adventure/war story. Katya's World has so many different twists and turns. We get new information at a steady pace that has us totally hooked in and begging for more. There's plenty of loyalty, betrayal, friendship, and even vengeance.I definitely recommend this book if you enjoy adventure stories and/or futuristic books about other 'habitable' planets. Katya's World is an interesting story that I greatly enjoyed reading! I'm really looking forward to finding out what happens in the rest of the series. The book gets wrapped up really well, but there are still plenty of openings for development in future books!
