Cloud Climber

What were his parents thinking, leaving him for three boring weeks at his grandparent's farm? There would be no internet or cable television and what was worse, only Cousin Emily for company. But on a trip to town with his grandfather, Seth learns of Three Friends Hill and the Banshee's Cave. Are these linked to the discovery of a giant kite Seth and Emily find in the old barn? The three weeks literally fly past and the cousins find that Boring Farm is not so boring after all.
