Unfortunately, our library only carried the first two books in the series, but I finally located the two 'Solar Queen' novelettes and read them, too. They weren't quite as good - Norton was concentrating on fantasy by then, and somehow it didn't quite mix with the crew of the 'Solar Queen'. However, I never lost my original affection for the series.
Then, decades after the publication of the original novels, I found 'Redline: the Stars'. I couldn't wait. I bought it in hardback rather than holding out for a cheaper edition. The fact that it had a second author's name on it was worrisome, but I assumed I'd be reading mainly Norton.
Not true.
I read the book from cover to cover, hoping to find at least a trace of Norton and a trace of the original 'Solar Queen', then hurled "Redline: the Stars" into the wastebasket.
I felt totally cheated. I usually give up my non-keepers to the library and loan my keepers to my friends, but I couldn't pass this one on to some other poor, unsuspecting Solar Queen fan.
I am pretty sure that all Norton wrote was the introduction to "Redline: the Stars". The original characters were passive, uninteresting shadows - even the Captain and the Cargo Master!. I felt like I was reading someone else's adolescent fantasy of the 'Solar Queen' and her crew that never should have been published under Norton's name. Nothing seemed 'true to life' (if I can use that phrase about something that was a novel to begin with). It was a horrible reading experience - the literary equivalent of visiting an old friend who has advanced Alzheimer's Disease. I don't recommend this book.
I enjoyed this book and went on to read the next in the series. It reminded me of the Star Trek original book series in that it takes reading several books for you to get to know the crew, and several books for you learn about why the Solar Queen is special. That is not immediately obvious in this book. But there is lots of action.
I recommend this book for teen readers who may be new to scifi and need to be "gentled" into it. No radical offworld ideas are set forth here. Good and bad are clearly identified, and sex is nowhere to be found.
The introduction of a female character made sense for a book written in the nineties, but why create one so offensive? Why not one better thought out? Why did Rael have to dominate the story, being the miracle cure for all problems, while whining way too much about how tough life has always been on her in spite of all the magical advantages she had?
Nonetheless, awful as Rael is, the book might have been tolerable if the other characters hadn't been pushed into the background and marginalized. The old main character (Dane) spent most of his time as a resentful nitwit. The shipboard niche Rael supposedly filled (medic) was already capably occupied by another character, who got shunted aside in her favor. The others were similarly treated. The only old character that got halfway decent treatment was the captain, and he was reduced to the role of Rael the Wonderful's love interest and sidekick. Gad.
I have to agree with the reviewer who described this book as "someone else's adolescent fantasy." That's exactly what it was. It's rare to see such a blatant case of "self-insertion of the author's fantasy self" in a pro novel. I can only attribute this nonsense to P.M. Griffin (whose other work I am unfamiliar with), since other Andre Norton books that I've read don't display this reprehensible trait.
For all you budding writers out there, this book is a perfect example of what *not* to do, unless you want to alienate your audience.
