From Liquid Passion:
Training’s over, and now the full-fledged members of the anti-terrorist zero unit are on active duty. Desk duty, that is. Lots of time for Shino to reflect on his fledgling relationship with his superior, TJ. Will he ever break through the older man’s reserve? Will Shino get tired of desk duty and stakeouts gone bust? When he spots a suspected terrorist on his drive through the city, will the lead turn into a career-making opportunity?
