Scientist Rayne Ryder has dedicated her life to studying Kaiju - the colossal beasts hell-bent on destroying the rest of humanity's twenty-one remaining cities. She just thinks they're neat! When her company discovers that she has an uncanny talent for piloting Machina, the giant robots used to fight the monsters one-on-one, her life is completely upended. Instead of staying in the comfort of the lab, she has to earn her place in the Crew of the best Machina operators Anchorage Protectorate has to offer. And her fiery new Shotcaller, Salem Voss, isn't going to make things easy on her as she struggles to adjust to her responsibility to fight the monsters she loves. Can she turn her knowledge of the Kaiju against them and bring herself to do what it takes to keep people safe - without losing herself in the process?
