What begins as childhood excitement transforms into something far more extraordinary when a genuine monster emerges, forcing young Gavin and the resourceful Debbie into an adventure they never imagined.

This imaginative tale explores how ordinary children face extraordinary challenges, discovering courage and cleverness within themselves. Written by Hugh Steadman Williams and beautifully illustrated by Margaret Gray, this enchanting story captures the wonder and danger of a holiday that becomes unforgettable.
