Styxx - Sherrilyn Kenyon If you thought Acheron's book was brutal, brace yourselves. Styxx's story is pretty unbearable. Pages and pages and chapters and chapters of rough. The 800+ pages read very fast and SK definitely had a story to tell for Styxx, but it isn't pretty or pleasant. You do get an HEA but she makes you worrrrrrrrrrrrrrrrrrrrk for it :)
