A Silent Killer

By Sekina Mayu

When their worst nightmare is haunting them again

Touka Kimizuki and her twin brother, Yuuto, were just high school students until they were recruited by the Public Security Intelligence Agency (PSIA) to work as secret agents. But after a failed mission, they find themselves in even more trouble when a hacker group exposes their top-secret project to the public.

As they try to figure out who is behind the leak, an unknown man starts pursuing them. But he's not just an ordinary person - he knows their past connection to the top-secret project and will stop at nothing to take them down. With their lives in danger, Touka and Yuuto must use all their skills to survive and uncover the truth behind their pursuer.

If you love the dark psychological and political thrills of Psycho-Pass, but want a fast-paced light novel with a focus on real-world espionage, the second book of the Trigger Locked series will keep you up all night.
