When marine biologist Ray Berringer and his student crew embark on an oceanographic cruise in the Gulf of Alaska, the waters are troubled in more ways than one. Ray’s co-leader, a famed chemist, is abandoning ship just as the ocean’s pH is becoming a major concern. Something at their university is corrosive, and it’s going to take more than science to correct. Powerful bonds are forged among offbeat characters studying the effects of ocean acidification on pteropods, a tiny, keystone species, in this cutting-edge CliFi novel. (Includes author Q&A and reading group discussion questions.)
