"Those sweet summer days seemed to linger forever. You remember. It was in that time before cell phones, electronic games, and helicopter parenting; when a garden hose was your water fountain, a bicycle your limousine, and you had to invent your own fun, using your own imagination. The books you checked out from the local library were printed on paper, with pages you actually had to turn, and smelled of musty adventure."

With these words we are launched into the exploits of an exceptional group of children as they play out through the Texas Hill Country and across the Blackland Prairies. Are they within the realm of science-fiction, or are they all simply due to drug-induced hallucinations that resulted from government- funded experimentation by a private laboratory, the University of Texas Psychology Department and the U.S. Air Force?

On the surface, two tales spin out—the children's search for what they believe was a flying saucer landing, and their parents' investigation into the drug experiments. Eventually the two come together, and the parents believe it's all over, but the kids know better.
