Illuminae

4.5 stars
I loved everything about this book: from the unique format to the gripping story and the amazing characters!
This book is very addicting- at times I couldn't stop reading.
The only problem I personally have with it & why I won't give it full five stars : As English is not my mother tongue I often found myself struggling with some tech words and being a bit confused.
But all in all I really enjoyed this book because it keeps you on the edge of your seat and you always want to know what happens next!
