Unlike most of Raymond E. Feist's books, this particular one lacked the typical fantasy element. It's important to note that this is a standalone sidebar to the Riftwar Saga, another series by the same author. While there were elves, dark elves, and some references to rifts, the book was predominantly pure fiction and action.
Fans of the Riftwar Saga might be disappointed as they won't see their favorite heroes in action. Instead, they'll find themselves immersed in an action-packed, fast-paced war fiction similar to the novels of Bernard Cornwell's Sharpe series. The author had explicitly stated that he tried to mimic Bernard Cornwell, and having read the Sharpe series, I would say he did a passable job. Due to the story plot, magic or spellcasting was non-existent as the majority of the Midkemian forces fought without its aid during the Riftwar.
Dennis Hartraft, the main protagonist, and his mercenaries were in the thick of a war against the Tsurani invaders when they suddenly found themselves facing a third party. Caught between divided loyalties and war-hatred, Dennis had to make a crucial decision to ensure the survival of his mercenaries.
In this book, fans of E. Feist will gain more insights into the Returning. It's a fantastic read on its own and the best book in the Legends of Riftwar series. I wholeheartedly recommend this book to war fiction fans.
