Damia (1992) by Anne McCaffey is the sequel that nobody asked for starring characters that nobody found interesting. Then, McCaffrey expanded the story, providing us with a novel full of filler.
Inside those bound, Damia continues the family story begun in The Rowan. We meet several characters, follow the development of both their personal and professional lives, culminating in a rehashing of the original short story, "Damia." The novel is almost entirely devoid of tension, anxiety, excitement, or charm. It just is. This is sorta the SF equivalent of an Epic Fantasy where you read about what every character does on making camp, day after day. What's there is all well written, but not engaging, possessing no momentum of its own. Damia doesn't even show until past page 100, over 1/3 of the way through the book. The characters themselves feel rather dull to the touch, like dough where the yeast has died off.
I'd love to say that expanding the story added something, deepened the setting, or increased our attachment to the characters, but it didn't. The whole thing takes place in the well run future, and the problem with the well run future is that there's really very little to sort out. The problems with this setting just overwhelm McCaffey's good intentions. I found little in the world that charmed me. Combine this with no knack for writing a family drama, and you get a novel that's pretty much dead in the water. Even so, the book is a marked improvement over The Rowan.
If you liked The Rowan, this book will continue to satisfy, possibly even more so. Otherwise, you're likely to get bored before the story gets anywhere, because the story really doesn't get anywhere.
