The Black Dragon

Love Slave
Saba Watanabe's enslavement to the black dragon, Malcolm, left the powerful witch shaken and vulnerable. But when she's assaulted by a white dragon in human form, the only one who can help her is the dangerously seductive Malcolm. With his attraction for Saba still at a feverish high, Malcolm agrees to help her track down the white dragon terrorizing the San Francisco streets.
Dragon Warrior
But Malcolm, too, has become vulnerable—victim of a spell cast to drain him of his strength—and Saba may be the only one who can rescue him. The key to their survival is in a mysterious book hidden in the world of Dragonspace. When its profound secrets fall into the hands of the enemy, the life of every dragon in existence is threatened, and Saba must not only battle her desire for Malcolm but learn to use her rising powers to save his kind.
