In this book, we follow Joe, a British slave in the French Empire’s England, as he journeys from London to a Scottish island and even through time to uncover his identity and a different future. The Kingdoms is a fascinating mix of alternate history, time travel, and adventure. The story explores the impact of war on a country and its people, while protagonist Joe unravels the mystery surrounding his past and his destiny. Although the plot can be a bit unclear at times, the book manages to keep readers engaged until the end. However, there are a few unlikable characters and an abrupt shift towards war that may disrupt the flow of the narrative. Nonetheless, if you’re searching for a mind-bending experience with a strong emphasis on atmosphere, this book is a must-read. Its unique experience is best felt rather than explained.
