The second Rain Wild Chronicles novel continues the dragon keepers' journey upriver as the relationship between keepers and dragons deepens and both begin to change in ways neither fully understands. The transformative power of proximity to dragons - the same force that shaped the Elderlings of the ancient world - begins to manifest in the keepers, raising questions about identity, consent, and what it means to become something other than what you were born. Alise's situation in Bingtown and aboard the Tarman barge develops in parallel with the expedition's progress, and the novel moves the dragons closer to the recovery of something essential that was lost to them. Dragon Haven is generally regarded as the stronger of the two expedition novels for the development of the keeper-dragon relationships.
