The Grey Star by James Bartholomeusz is the third book in the Bartholomeausz's Seven Stars Trilogy. The main characters have to face the evil Cult of Dionysus while trying to find an old friend. There are suprises everywhere that all of the main characters face, including a revered "master" turning into an evil leader. The characters perservere, and make it to a special mountain, where a greater suprise awaits them. Will they survive?
The Grey Star was action-packed, but it kept switching between characters too often. I liked the book, but I failed to understand it because I had not read the previous two books. I would recommend others read the first two books in the trilogy, The White Fox (number 1) and The Black Rose (number 2) before they read The Grey Star.
