Of the 5 or 6 of Piserchia's works that I've read (so far) nothing gets less than 5 stars, but with that in mind I would rate Spaceling (along with A Billion Days Of Earth) an easy 7 [out of 5] stars! With characters that could be the inspiration for illustrations by the likes of Basil Wolverton, Wally Wood, Norman Saunders or Bernie Wrightson, Doris Piserchia was delving into uniquely imagined worlds set well apart from her more often read 1970s science fiction contemporaries.
Sadly, all of her work is 'out of print' so the copy I read was a public library/inter-library loan, but I think I'm going to hunt up a used copy as this is one of those rare finds which I may be compelled to re-read, or at least loan to deserving friends. There are also sections of Spaceling that were so poetically striking I'm thinking I would like to commit them to memory:
"In the Universe through which I traveled, nothing was stationary but all was in motion. Little bits of matter were as significant as worlds because I could discern them and comprehend the service they rendered.
"Here the planets spun so fast they resembled flat discs falling like a never ending row of dominos. The colors of the rainbow were everywhere around me, pastel and glittering, flashing past me like an assembly line of fragile pieces of light. Earth was a revolving coin that enveloped me, appeared to flash on over my head and then was gone..."
Very beautiful stuff! And the story's momentum is never compromised, it remains a fast paced mystery/thriller embodied in a thought provoking hunk of sci-fi.
