Blood Island

From publisher blurb: You are the key biologist aboard a research vessel named Albatross III, headed into the Pacific from San Francisco. Midway through your 5-day voyage, the crew reveals their anxiety about your destination: Blood Island. It is a legendary place, difficult to reach and with a propensity for conflict, murder, and insanity logged during the rare visits to its shores. As if that wasn't enough, Blood Island is also home to a life-threatening volcano with a record of unexpected eruptions. You and your team are skilled, but will you all survive?
