Transported to the magical land of Bren, The Jennings kids must fight for the life of their grandfather, King Leonolis, and for the freedom of the land of Bren.

The evil sorcerer, Sepeleo Parkinson, has cast a crippling spell, called a mind claw, over the mind of the king. Though the spell is unbreakable, the children are tasked with seeking a way to save the king and bring freedom to Bren in the process. To do so, the children are each given puzzle pieces of their lives along the way.

Will they be able to uncover all the missing pieces and complete the puzzle in time?

With so many new foes to face and puzzles within puzzles to solve, the Jennings kids must stay united for the King's life to be spared.

The Puzzle is the third book in The Bairns of Bren series, which tells the tales of the many adventures of the Jennings cousins in the land of Bren - the place where it is Christmas all year `round.
