Light by the British author M. John Harrison is a dark and sometimes violent meditation on how we encounter the incomprehensible. Three strands follow the protagonists weaving the novel.The three twisted characters, including one who brutally murders women to escape his fate, never meet but are responding in different ways to a massive trench of alien artefacts that cannot be understood, just pirated. One of the best of that strain of dark Brit sci-fi/fantasy that includes Ian M. Banks and China Mieville.
