Now, I have read the Goosebumps book One Day at Horrorland more than once, and I think it's really neat, as well as highly well-written too.

Basically,  the 12-year-old protagonist, Lizzy Morris, her parents, her little brother Luke (who is 10 years old and said by Lizzy to have too much energy) and Luke's best friend Clay (whose surname isn't given), are going on a family trip to Zoo Gardens Theme Park. However, Mr. Morris messes up and forgets the map by leaving it at home. (Dad, get it together.) So, as a result, they get lost in the middle of the desert. Soon, they see a billboard for another theme park — which happens to be called HorrorLand.

"Can we go there?" Luke demanded eagerly. He leaned forward and grabbed the back of Dad's seat with both hands. "Can we, Dad? How about it?"

Dad slammed the glove compartment shut with a sigh. He was giving up on the map idea. "Luke, stop pulling my seat," he snapped. "Sit back."

"Can we go to HorrorLand?" Luke demanded.

"HorrorLand? What's HorrorLand?" Mom demanded.

"Never heard of it," Dad muttered.

"It's only a mile from here," Luke pleaded. "It looks great!" (p. 10-11)

At first, only Mrs. Morris is against the idea of going to HorrorLand:

"I don't think so," Mom said, staring out at the huge billboard. "Zoo Gardens is a wonderful park. HorrorLand doesn't look very nice." (p. 11)

But they eventually decide to head there on Lizzy's advising them to try their hand at it:

"Let's give it a try," I urged them. "If we hate it, we can always leave."

Dad rubbed his chin. He sighed. "Well, I guess it would be better than sitting here in the middle of nowhere arguing all day." (p. 11-12)

However, their jolly family vacation is then ruined by a series of horrific theme park rides, each one more deadly than the previous. The park's employees, who are appropriately called HorrorLand Horrors, capture the family and force them into a monster game show that tortures humans on TV. The whole point of HorrorLand is, nobody gets out alive.

If you want to find out what happens next, read the book.

I highly recommend this book to anyone who likes a good scare, and I give it five stars (although ten stars would be even better).
