In this hardbound edition of novel 23 in this series, Tom must travel to Mars to find out just why the small moon, Phobos, has suddenly begun coming close to the surface. In fact it is coming down to lower and lower orbits that could, within months, endanger the colonists on the planet below. He first tries to use brute force and to push it back into higher orbit, but nearly loses several spacecraft in the attempt. So, he now is faced with finding out the why of it all before he can find a solution that won't mean simply destroying the moon. That, he fears, might backfire and do damage to the colony and the planet. He tries to find some answers with the aid of his Space Friends, but they seem to have disappeared from his life. Without their help he mounts an expedition of Phobos and finds about the last thing he might think of. Now it is a race against time to see if he can rectify the situation and re-place Phobos in its correct orbit.

From the bestselling author of The Man Who Mistook His Wife for a Hat • Fascinating portraits of neurological disorder in which men, women, and one extraordinary child emerge as brilliantly adaptive personalities, whose conditions have not so much debilitated them as ushered them into another reality. Here are seven detailed narratives of neurological patients, including a surgeon consumed by the compulsive tics of Tourette's syndrome unless he is operating; an artist who loses all sense of color in a car accident, but finds a new sensibility and creative power in black and white; and an autistic professor who cannot decipher the simplest social exchange between humans, but has built a career out of her intuitive understanding of animal behavior. Sacks combines the well honed mind of an academician with the verve of a true storyteller.
