The Dragon Keeper, by Robin Hobb
She had us at dragons.
They’ve returned to the Rain Wild, but they’re hatching out weak and deformed, unable to fly. The once-magnificent beasts are too dangerous to keep, too important to kill. So a rag-tag team is chosen to take them back to their fabled home upriver.
These human strangers don’t know where they’re going. They don’t even know if they’ll survive. But they have one chance to make a difference—to save dragonkind from a world that has forgotten its past—and they have to try.
