'I don't know when I last read a book with such pure and unalloyed pleasure. It's ingenious, it's moving, it's charming, it's beautiful, it's exciting, and most importantly the characters are people I feel I know like old friends. I thank Jakob Wegelius wholeheartedly for giving me several hours of joy." - Philip Pullman

Sally Jones is not only a loyal friend, she's an extraordinary individual. In overalls or in a maharaja's turban, this unique gorilla moves among humans without speaking but understanding everything. She and the Chief are devoted comrades who operate a cargo boat. A job they are offered pays big bucks, but the deal ends badly, and the Chief is falsely convicted of murder.

For Sally Jones this is the start of a harrowing quest for survival and to clear the Chief's name. Powerful forces are working against her, and they will do anything to protect their secrets.
