This is a second in the series that started with Hook; Whirlpool of stars. It is classic sci-fi from the 70's which my father would have called a 'pot-boiler' . It is very much a stereotypical adventure with a stereotypical 'man's man' type hero and you are going to thoroughly enjoy it for what it is (much like the hysterically funny cover art) or you will probably hate it.
It almost does not matter what the plot is but here: the century is 10,000 Earth dating, humanity have spread into the galaxies and stars, there are dozens of human, alien and (?) all sharing the galaxy. In amongst all the civilised humanity is Ryder Hook, a fierce independent man with a history that seems to keep chasing him around the galaxy and a penchant for getting into trouble of the more martial type.
It is dated a hokey, the author was 'prolific' according t Wikipedia and that almost certainly means he was a rote writer.
In fact the series reminds me an awful lot of the The winds of Gath books by E. C. Tubb, so much so I googled to see if the pseudonym Tully Zetford (come on, that is pretty obviously a pseudonym) might be from the same author. It wasn't by Tubb and Bulmer were both UK sci-fi writers of the same era and appeared in many of the same compilations. They must have know each other and it would be interesting to know how the two series influenced each other.
This one is only really suited for people who, like myself love the trashier types of 60's - 70's sci-fi. Also on YouTube https://www.youtube.com/watch?v=wUJE1...
This was the first sci-fi novel I read as a youth and I loved it at the time. In retrospect, it's not that strong, but it got me hooked on reading sci-fi at the time and deserves three stars for that.
