Loren Van Zant, Mutiny on the Mohawk (2016). Space opera with wampum currency. "Sinister crouched down into a cocorinha, a squatting escape maneuver, and the holographic Yoruba god curled back upon himself in a spiraling whir. There was another surging roar and this time Sinister could distinguish individual bets being shouted out in wampum denominations." (loc. 740-743).
