"The legendary dragon city of Kelsingra has been discovered. But most of the dragons now lack the strength for the final hazardous river crossing, and the mythical sliver wells they need to survive are nowhere to be found. In a desperate attempt to unlock the whereabouts of the wells, the keepers risk 'memory walking'--immersing themselves in the drug-like memories of long-deceased Elderlings. The magic of the city and the final secret it conceals...

Continuing the enthralling journey she began in her acclaimed Dragon Keeper and Dragon Haven, Hobb rejoins a small group of weak, half-formed and unwanted dragons and their displaced human companions as they search for a legendary sanctuary. Now, as the misfit band approaches its final destination, dragons and keepers alike face a challenge so insurmountable that it threatens to render their long, difficult odyssey utterly meaningless.
