The stardust grail
(Book)

"Maya Hoshimoto was once the best art thief in the galaxy. For ten years, she returned stolen artifacts to alien civilizations--until a disastrous job forced her into hiding. Born off-world and infected by an alien virus from a young age, she receives the occasional vision of the future. Now she just wants to enjoy a quiet life on Earth as a graduate student of anthropology. Until an old friend comes to her with a job she can't refuse: find a powerful object that could save an alien species from extinction. Two problems: no one has seen it in living memory, and they aren't the only ones hunting for it. Maya sets out on a breakneck quest through a universe teeming with strange life and ancient ruins. But the farther she goes, the more her visions cast a dark shadow over her team of friends new and old. Someone will betray her along the way. Worse yet, in choosing to save one species, she may doom humanity and Earth itself"--,Provided by publisher.
