PEREGRINE (1977) by Michael Whelan

At first glance the book Peregrine looked like an original publication from 1978 but that didn’t track with the fact that Michael’s early ACE covers for Poul Anderson were all reissues.

Sure enough with a little research on ISFDB and Wikipedia, it appears this was a repackaged version of Star Ways from 1957, book 6 in Anderson’s Psychotechnic League.
