The Swivel-Eyed Ogre-Thing

In an alternate 15th century, where dragons roam, sailing ships transform into submarines, and blacksmiths build steampunk robots, ten-year-old orphan Benjamin Blank battles monsters, rescues people in peril and discovers fantastic new lands, but never quite manages to get his homework handed in on time.
In his second adventure, when local trolls start disappearing, Ben suspects foul play and sets off to solve the mystery. And that’s how he meets the SWIVEL-EYED OGRE-THING. And gets a bit more fighting and danger than he’d bargained for…
An hilarious series from Barry Hutchison, perfect for fans of Beast Quest, and brilliantly illustrated by Chris Mould.
