In the small town of "Monchaville" where the MONCHA HQ is, bakus are the thing and Profectus Academy is the school. 7th grader Lacy Chu, dreams of becoming a companioneer for Moncha, the company that created the baku, a robotic animal pet that is well known, but when her acceptance to Profectus is turned down, she is wrecked. One day, when she is down in a ravine looking for her friend's baku, who had fallen in, she finds a pile of metal which she figures she can use for spare parts to aide her tinkering hobby. But later, when she is starting to take it apart she makes an amazing discovery, a face. And to her surprise, later she gets a email accepting her into Profectus. As she starts to fix her metal face findings, she fixes it back into a high level cat baku. Life at Profectus is crazy, especially with a definitely not obedient cat baku she names Jinx and getting picked for a baku battle team. This is a must read book, and I just had to get past a little slowish part in the beginning and then I was hooked (same thing with a small part in the second half)! Recomendend for anyone who love STEM, Technology, battling, and mystery.
