The Secret Library

At Enchancia Castle, Sofia is having a flying derby race with her friends, when suddenly Aunt Tilly arrives and pays a visit. Upon arriving at the castle, Aunt Tilly asks Sofia about how she's doing with the book she gave her and reminds her to read Chapter Seventeen, which is her favourite. Sofia later goes to her room and reads more of the book and finds a small blue book that tells her about secret passages inside the castle.
