Damocles by S.G. Redling

When Earth is rocked by evidence that extraterrestrials may have seeded human DNA throughout the universe, a one-way expedition into deep space is mounted to uncover the truth. What linguist Meg Dupris and her crewmates aboard the Earth ship Damocles discover on Didet—a planet bathed in the near-eternal daylight of seven suns—is a humanoid race with a different language, a different look, and a surprisingly similar society.
But here, it’s the “Earthers” who are the extraterrestrial invaders, and it’s up to Meg—a woman haunted by tragedy and obsessed with the power of communication—to find the key to establishing trust between the natives and the newcomers. In Loul Pell, a young Dideto male thrust into the forefront of the historic event, Meg finds an unexpected kindred spirit, and undertakes an extraordinary journey of discovery, friendship, and life-altering knowledge.
Told from both sides of a monumental encounter, Seven Suns is a compelling novel about man’s first contact with an extraterrestrial race.
