Here is what a Reviewer said:

Extending from her Zeeka and the Zombies trilogy is Mohammed's most nostalgic offering, Zeeka's Ghost. Zeeka is back but not at all how you expect. Unresolved issues, regrets, and love are all splendidly woven together with the right mix of startling plot twists the author is masterful at. Fans of the series will not be disappointed and new fans will be caught up to speed in no time. Another thrilling read! [Amazon Reviewer]
