The Dolphins of Pern (1994) by Anne McCaffrey is perhaps the beachiest beach read of all her Pern books. It turns out that the Pernese people have yet another thing that they've forgotten about, the intelligent speaking dolphins that came with the orignal colonist. Why the dolphins just didn't shout out, "Hey, you stupid two leggers. How about some fish?", I don't know, but Pern folk are mighty dense, so I rolled with it.
The story itself wanders all over the plays, swaps between main characters a few times, and even has a subplot with no relationship at all to the main plot. (It's Toric again. Same stuff.) It won't hold its place as one of the best dragon rider books, but it's a relaxing read, the characters are generally pleasant and not too stupid, and everyone goes about the same songs and dances as always. If you like the Pern books, this book will itch all the right places.
At this point, I believe that Anne's overall cognitive skills are showing decline. For her career at Del Rey, she'd had great editorial support, but her novels contemporaneous to this one show far weaker story, sometimes to the point of having no actual plot arc. From here, the amount of outside support that needs increases steadily, even if their names are not shown on the cover, putting this book on the tail of of the pure McCaffrey Pern novels. From here on out, she will write novels with co-writers.
In many ways, this book is Anne McCaffrey's greatest hits. You see all her favorite story ideas collected into this narrative, and you'll be able to identify which books they come from. There's nothing really new here. We see many of our favorite characters walk in for a chapter or two, making for nice visits from old friends, although some of these possible plots get dropped as the story progresses.
While the book threatens to fail as a narrative, Anne's Pern has enough internal conflict and stubborn characters that's there more than enough plot to sort out. It's all done rather pleasantly, with some ups and downs along the way. AlI said, it's a beach read. Nothing about it is difficult. It's distracting enough to be distracting, but not so engrossing that you forget to check whether your kids are still alive.
