As a 40-something male, I am clearly not in the target demographic for Jennifer Roberson's DEEPWOOD. In contrast to other reviewers, I found DEEPWOOD even slower and even more disappointing than KARAVANS. Readers who just want to know what happens after the end of KARAVANS should consider a quick skim in the bookstore.
Those who read KARAVANS will recall that Audrun and her characterless children have become trapped in wondrous, dangerous Alisanos. What happens? They run around panicking, they say and do stupid things, and they get knocked around a bit. What do we learn about Alisanos beyond what we already knew in the first few pages of KARAVANS? We learn a little about its gods, we learn that it has dryads and dragons, and that's about it. (I don't want to knock the gods' part too much--that's one of the more interesting bits of the novel.)
Ilona, the most appealing character in KARAVANS, gets relatively scant attention in DEEPWOOD. I think that's a mistake. She comes back into the story at the end in a big way, but that doesn't make up for her limited role early on. Rhuan, the demigod who likes humans, gets plenty of play, but there's little character development; in fact, his strong-but-sensitive guy act becomes even more generic here. Brodhi, Rhuan's disdainful cousin, thankfully does develop a little, displaying a little more compassion and fellow-feeling than he had in the past--not that he would admit feeling it.
The book also follows the efforts, led by brave courier Bethid, to rebuild a settlement thrown into chaos by the movement of Alisanos and by the Hecari's earlier decimation of the population. While Bethid's efforts are admirable, it's hard to see this part of the story as anything but a sideshow.
I don't think that Roberson is necessarily a bad writer, and if she had an incentive to do so, she could probably have written a book that was twice as good and half as long. I think market demands for long series of long books is as least as responsible for the tediousness of DEEPWOOD as are Roberson's skills, inclinations, and imagination. Nevertheless, it is what it is, and I do not recommend it.
