In it he keeps the very special book that Grandad gave him to help him to learn about the Person who made the whole world.
But it's not just any book - it's a portal to Bible times.
Join Harry in his first adventure, Spot the Difference, in which he finds out how the disciples came to be Jesus' special friends and how being chosen by Jesus made them feel.
In The Big Splash Harry finds out what happened to Peter when he walked on the water.
Suddenly, getting into trouble for falling in his own paddling pool is not so important as Harry realises that Jesus understands our mistakes.
