Bronte Tempestra is ready for adventure at Sir Sebastian's School for Squires! It's not supposed to snow in the Heart of the Kingdoms, but Sir Sebastian's has been turned into a snowy wonderland - and it looks like the knights will be stuck at school for the holidays! Breezy! Then some ice sculptures come to life and Bronte realises she has another quest on her hands. As she ventures through deep tunnels and into the heart of a blizzard to confront her frosty foes, Bronte shows she's more than a knight - she's a hero!
