Hobb wraps up her "Rain Wilds Chronicles" fantasy series, intriguing because the dragons featured arent trouble but in trouble-they will sicken and die if they dont reach the lost city of Kel-singra. Finally, theyve made it with their keepers, who are beginning to exhibit markings that link them to their dragons. But the silver wells the dragons really need still cant be found, so the keepers must do a bit of risky memory walking.
