LASOMBRA is the sixth novel in the Clan Novel series that began with TOREADOR and will continue until it reaches thirteen volumes with a bonus anthology. It is the trademark series of Vampire: The Masquerade and was written roughly between the end of 2nd Edition and the beginning of its Revised. Gehenna, the apocalypse of vampires, is nigh with a war being fought between both the Camarilla (evil vampires) and the Sabbat (eviller vampires).
CHICAGO BY NIGHT 5TH EDITION is technically the third edition of the seminal Chicago by Night city book supplement for Vampire: The Masquerade. Way back in 1991, the book was released for the then-new series about playing tragic misunderstood creatures of the night a decade before Twilight made it uncool. The book was a shocking change the kind of books present from Dungeons and Dragons or even Call of Cthulhu. It was adult, edgy, racially diverse, sexually diverse, and full of complicated politics your player characters were meant to involve themselves in without shooting up the place. Well, yeah, they'd probably shoot up the place anyway but it wasn't advised.
CLAN NOVEL: VENTRUE by Gherbod Fleming is the fifth novel of the Vampire: The Masquerade Clan Novel series. It is a series published in 1999 and told a thirteen novel story about the conflict between Sabbat (bad vampires) invading the cities belonging to the Camarilla (less bad vampires). A magical artifact called the Eye of Hazmiel was serving as a wild card during it and each new book's protagonist was a glimpse into one of the individual undead's journey. Each book also served as an illustration about what a specific clan was all about.
