IN CASE OF MEDICAL EMERGENCY, CALL TAYLOR'S ARK...

It's the most unusual medical unit in the galaxy--and it makes house calls. A fully equipped starship lab, Taylor's Ark is run by Dr. Shona Taylor and a menagerie of very special assistants--including a cat, a dog, rabbits, mice, and an alien ottle named Chirwl...

Now, this highly trained crew faces the ultimate medical mystery. On Chirwl's home world, humans and aliens are aging at an alarming rate. And if Dr. Taylor doesn't find a fast cure, the entire colony will die...of old age.
