Black Carnival. The Cydonian Tales, #1

The city of Venice has been rebuilt on the far planet of Cydonia. Despite the uneasy presence of the mysterious, only part-human Sand Riders who roam the Cydonian deserts, The Black Carnival has become a celebration of beauty and lust known all over the Galaxy. Ivory Blake, a young artist from the conservative Central Planets, is thrown in the middle of the festivities to illustrate a new book about the Black Carnival.
As a guest of the glamorous art collector Lukan Løvensgård, her professional assignment quickly turns into a highly emotional exploration of sensuality in all its most varied aspects, from BDSM to romantic love, passing through obsession, fear, jealousy and passionate, tender complicity.
