JINCAN, a deadly toxin created through sorcery by combining the venoms of five creatures, oozes through the pores of this thriller - set in China, the jungles of Panama and the gold country of California in 1850.

Shen, a Chinese assassin escapes to America with dreams of riches. Angus Greystone is a lawman on the hunt for the truth behind President Zachary Taylor's sudden death. Shen and Greystone collide in a muddle of cross-cultural mishaps before forming an unlikely partnership to track the culprit down together, trailing a killer into the Sierra Nevada where the hunters become the hunted.
