The book you are holding is called The Three Billy Goats Gruff. The story was first written down in Norway almost 200 years ago. It has been told, over and over again. Here is my version -- Adapted from inside cover.

Once there was a bridge and a terrible and VERY hungry troll lived underneath it. When the three Billy Goats Gruff decide to clip-clop across the bridge to get to the grassy ridge, the troll is already imagining all the way to prepare a delicious goat dinner. But the troll underestimates those seemingly sweet but oh-so-savvy goats!
