The Fear Zone by K. R. Alexander (author) (UK edition)

If you don’t stand up to your fears, they will destroy you. When five kids are invited to a cemetery at midnight, they think it’s just a prank. When they find a gravestone that instructs them to dig up a grave, they think it’s just a joke. It’s no joke. An evil force is unleashed – a force that takes the shape of their worst fears.

• A shark in the water.
• A ghost in the walls.
• A nightmare of being buried alive.
• A snake about to strike.
• A sinister clown waiting in the woods.

Once these fears are released, they won’t go away. Not without a fight. . . .
