A boy and his pet, or vice versa, head out to the woods for a little alone-time from the stresses of societal demands... I think I only read this one five times since junior high. I love the teen girl divorcing her parents in a 1954 book!
Twins with telepathic talents maintain communications between a spaceship surveying planets to settle and Earth. Read again. And again. This time I learned that "sasparilla" is a variation of the original "sarsaparilla". Or vice versa. Or neither!
