Sunlight — C.L. Bledsoe

The sunflower farm was the most boring place on earth. Until weird things started happening...

What's the most boring place in the world? The farm. After his mother's death, Sol is sent to spend the summer with his aunt and uncle, but with no cell service and only an old dinosaur of a computer, Sol's not sure how he's going to survive. But his boredom is interrupted by strange sounds at night, the discovery of a mysterious cave, and stuff that starts to sound an awful lot like a bedtime story his mother used to tell him when he was small...that just might be true...
