Sarah Long, a junior geologist on a sonar vessel makes the discovery of a lifetime. A strange ship buried in the seafloor of the Pacific Ocean. It's impossibly big. Extremely old. And most definitely not from this planet. But neither is it alien. Or dead. At the same time, the ship makes its own jaw-dropping discovery, and captain Jan Argen must decide between his duty to the ship's mission and a shocking, new reality he never expected. Moving between characters anchored in contemporary, American life and the crew of the interstellar ark Kalelah, a culture without time, living lightyears from its home world, Lost Arrow is the start of a thrilling countdown toward a battle between humans who have everything in common, except what they believe.If you love Ted Chiang's ability to leave you wondering what would happen if everything we thought were true suddenly wasn't, you'll love this fast-paced sci-fi thriller.
