'In a world where the law is often more corrupt than those breaking it, sometimes you have to take justice into your own hands.
'Rosie doubts her ability to find a submersible they've been hired to locate, even with the help of her companions. After all, how can anyone track across the water? She quickly learns the submersible isn't all that is missing and ends up searching for a girl, a murderer and trying to unravel the mystery surrounding an engraved bracelet. Rosie needs to complete the job they were hired for, find answers and locate a dangerous war mech or risk cities being annihilated when someone seeks vengeance for the past.'
