Ian White lives under the thumb of his scheming uncle Mawson in Blackstone City, an isolated bastion threatened by catastrophic centennial monster invasions. Since his parents' mysterious deaths eight years ago, Ian has kept a low profile, waiting for the magical seal suppressing his inherited beast-taming powers to expire on his eighteenth birthday. With only fifteen days remaining, his uncle conspires with shadowy cartels to trigger an early monster breach.
Refusing to let innocent citizens perish while he waits in safety, Ian creeps onto the barricades to command savage predators in secret. His miraculous battlefield interventions catch the attention of elite beast tamers, who draft him to lead the city's final defensive stand. Ian must outsmart his treacherous kin before the gates shatter under the onslaught.
