Time Trap

"Dano was a hopeful, a Teen, with a skimmer that could do 100 mph and all the sports gear in the Catalogue, but it was not enough. He wanted to get out of Homebody Unit 362 and be responsible for his own life, and perhaps Uncle Lipton, with his secret long-life drug, Xtend, might have the answer." - From the back cover of the 1987 Penguin edition, via Google Books.
