I think Goosebumps Horrorland is a great book which is packed with 3 brilliant stories. One is called Creep From The Deep which is a great story full of gore, action and terrifying chapters. This book is excellent and I would recommend you to read it as it is a great book.
I will tell you a bit about the story to get you more interested...It begins with a boy, his sister and his uncle going on a pirate ship which has not been discovered for 200 years! When they found it, their uncle disappeared. Find out how the story ends if you read the book.
