The Coach with the Dragon Tattoo

That week, Ram witnesses a creature slaughter both the assistant coach and a school cleaner, but struggles to find evidence of their deaths after the fact, leading him to question his sanity.

Tanya, Charlie, and April investigate on his behalf, and learn that a dragon manifesting in different parts of the school is connected with Coach Dawson.

They learn that the coach was bound to a female dragon who came through a rift in time, and became fused to his body as a tattoo; its mate roams the school, killing in order to feed her.

[3] In a very positive review, Flickering Myth stated "Class takes the smarter route, here, in letting the friendships grow more naturally from other aspects of the characters’ lives.

Indeed, it’s really nice to see Class placing characterisation front and centre, repeatedly emphasising the development of our core cast; it’d be very easy to coast in this department, and leave our characters as more typical young adult fiction stereotypes and shortcuts.
