The Rowan (1990) by Anne McCaffrey is an expansion and continuation of the Rowan story found in Get of the Unicorn, a collection of stories written in the 1960's.
There are two ways to expand a story: rewrite it or extend it. Anne chose to extend, keeping her story from the 1960's intact. This choice that Anne kept all the weirdness and kludginess in the original SF romance story, with all the complication of setting up a larger story around it. Because of this decision, and her limited narrative skills, the results are largely a failure. Indeed, the later half of the work reads largely like documentation, sending the characters here and there, seeing them do things, and no parts of the story hanging together at all.
Personally, I blame continuity culture. Anne should have taken the original story and completely rewritten it within so that the entire story works as a novel, revising or revisiting the dated tropes of the original story. Instead, she accepted her continuity as inalterable, which meant that she left herself with all the bad decisions inherent in her original tale.
The cover for my version is gorgeous, a bright vision of SF that we don't get to see any more. The Rowan herself appears with huge guzumbas, thin arms, and shapely legs. The the faint face of a man on the cover, it gently hints at romance. But hey, look at those gazumbas!
While I absolutely adore Anne at her best, at her worst, she's a waste of ink. She's the Lucy to my Ricki and she drives me baba-loo. This manuscript leaves me ranting in faux Cuban Spanish. How did Anne's madcap plan go so wrong? Not only does this book feel dated for the late 80's/early 90's, it feels dated for the mid-70's. Anne's work in the 60's feels a little dated for the 60's. Even if you can get over the dated feel, the architecture of the novel doesn't even work. The sections aren't workable stand-alone stories, and the stories together don't add up to anything at all. What we're looking at here, folks, it a literary McMansion, a total failure of architecture at every level.
The only reason that I don't give the book one star is that I've read one-star books, and even being a failure at every level, this book is still better than a one star book.
