It’s not merely sci-fi, but a thriller wrapped in the deadly solitude of space with a determined heroine who refuses to give up.” —New York Journal of Books “Joe Hart is a tremendous talent, and with Obscura, he has taken his storytelling to the next level. This is a genius work of science fiction, brimming with thrills, scares, and most importantly, heart.
