Tymora's Luck. Forgotten Realms

Before the Dawn Cataclysm, Moander the Darkbringer corrupted Tyche, Goddess of Luck. In a desperate attempt to preserve Tyche's goodness, the gods clove her in twain, creating two daughter goddesses: Tymora, Lady Luck; and Beshaba, Lady Doom. In the eons since then, the two sisters have existed in total enmity. Now a great power has hatched a mad scheme to re-create the goddess Tyche by reuniting Tymora and Beshaba, regardless of the potentially calamitous consequences.
In a decision fraught with godly intrigue, Joel, the Rebel Bard, priest of Finder, is chosen to uncover whoever is behind the abduction of the sister goddesses. Aided by his old allies, Holly Harrowslough and Jas, and his new friend, the kender Emilo Haversack, Joel must find a way to prevent the merger of Tymora and Beshaba before disaster overtakes the luckless Realms. The Forgotten Realms meet Dragonlance meet Planescape in a heart-stoppin gadventure that spans three worlds.
