Quick Review of Specter of the Past
by Timothy Zahn
In the deft hands of Timothy Zahn, any Star Wars novel is a delight. This is book one of a duology featuring the return of Thrawn about ten years after his (apparent) demise. The second book is titled, Vision of the Future.
The Empire's Grand Admiral Thrawn first made his appearance in Zahn's Heir to the Empire trilogy which is set about 5 years after the story in Star Wars Episode VI.
I still want to read Zahn's latest book, Thrawn, where he "chronicles the fateful events that launched the blue-skinned, red-eyed master of military strategy and lethal warfare into the highest realms of power—and infamy." (from the publisher's blurb)
