Death Waits in Semispace

BETWEEN DIMENSIONS! DIMENSION 4...DIMENSION 5... AND SOMEWHERE IN BETWEEN–SEMISPACE!The unknown realm of the halfplane must be penetrated if the planet Wanderer is to be reached in time. For it is the year 2042, the critical date when Perry Rhodan and Reginald Bell must have a biological booster from the physiotron on the artificial world: without the cell shower renewal they will degenerate into old age!  The venture between the dimensions turns them temporarily into giants who cause devastating storms as they cross an entire ocean with one step!  But even giants can be felled (as David demonstrated to Goliath) and our intrepid Terranians discover that—DEATH WAITS IN SEMISPACE!
