Welcome to Ballydoon, from Terry Deary, author of Horrible Histories

Brigid Leary knows that Ballydoon School is a bit strange. For one thing, her teacher hasn’t turned up because she’s too busy hunting for the Yeti in Nepal! So when Brigid’s friend Seán goes missing, she knows it’s up to her to find him. Searching for clues, Brigid ends up on a treasure hunt at the mysterious ruins of an old Norman castle. What will she find inside?
