Martian Time-Slip by Philip K. Dick

1st US printing. 1964 Ballantine mass-market paperback in fair shape. Mild-to-moderate shelf wear on the extremeties, a couple of dings on the cover.  Slight warping from heat, no water damage. Good price for a hard-to-find edition. 
 
On the arid colony of Mars the only thing more precious than water may be a ten-year-old schizophrenic boy named Manfred Steiner. For although the UN has slated "anomalous" children for deportation and destruction, other people--especially Supreme Goodmember Arnie Kott of the Water Worker's union--suspect that Manfred's disorder  may be a window into the future. In Martian Time-Slip Philip K. Dick uses power politics and extraterrestrial real estate scams, adultery, and murder to penetrate the mysteries of being and time.
