Knightley Academy

Henry Grim has never been in trouble for borrowing a sword from the headmaster's private stores. He has never discovered a forbidden room in a foreign castle, or received a death threat over breakfast.
All Henry knows is life as an orphaned servant boy at the Midsummer School, bullied by the privileged sons of aristocracy. But all that changes when Henry is the first commoner to pass the entrance exam for the prestigious Knightley Academy, where he will be trained as a modern-day knight alongside the cleverest and bravest fourteen-year-olds in the country.
