This book was so much fun! It's set in a futuristic world where everyone has a "baku", which is like a smart phone but shaped like an animal that is the perfect, little companion. Lacey Chu dreams of one day working for MONCHA, the huge tech firm behind Bakus, and to do so she needs to get into the prestigious Profectus Academy. However, Lacey can only afford a Level 1 Baku that isn't good enough to get into the Academy. But then Lacey stumbles upon a broken cat baku that's surprisingly advanced and she suddenly finds herself accepted into the Academy of her dreams. And thus begins a fun adventure full of twists and turns as Lacey meets friends and enemies at her new school, puts her mechanic skills to the test with baku battle training and discovers that this little cat baku she found might actually be a part of something much bigger than she ever could have expected.
