These are the ONLY novels written before TSR cancelled the Spelljammer AD&D campaign:
In this, the third novel of a 6-part series, the main character (Teldin Moore, a native of Krynn, the Dragonlance world) meets with the Elven Imperial Navy to get help in determining the properties of his mysterious cloak, which is said to have ties to the Spelljammer ship itself.
As the story develops, he is emroiled in a conflict with the elves and the Scro, an intelligent orc race, who both want to obtain his cloak (as does an undead neogi). Along the way, he is reunited with a character from the first book (a hippo-man named Gomja) and is joined by a native of his homeworld, a female half-kender (as he would say, "Great Paladine!").
Well-written and in-depth, this continues the series of novels about the Cloakmaster. Each novel is written by a different TSR-native author. The story, so far, has meshed well and each author well-defines the broad scope of the unique Spelljammer setting.
This entire series must-buy for a fantasy fiction lover tired of the traditional "Earth-style pseudo-medievil world-walker" campaigns.
