Orphaned in the desolate Lost Ghetto of Mekanus, Jurdan and Sarann have fought for survival every day since their childhood. Struggling to deal with the threats of Nocturnals and the deadly street gangs who dominate the ghetto, the pair plot a dangerous plan to lead them out of the Lost Ghetto and into the greater world of Aden, a world they know nothing of. There they encounter allies and enemies, discover that the world is not how they believed it to be, and find a cause that is greater than themselves. Indomitable Thunder is one of three novels set in the intriguing world of Aden, first seen in the bestselling computer game Thunderscape. The world Sarann and Jurdan belong to is a fascinating one, and Acres captures the feel of it extremely well. The characters react in believable ways, and almost everyone can identify with someone in the book. The plot against Lord Urbane's secret project is well-laid out, although the conclusion of the novel seemed somewhat rushed. If Acres had an additional twenty or thirty pages to flesh things out, then this could easily have been a 4 or 5 star book. As it is, I enjoyed it quite a bit, and was surprised to see how quickly I finished it. If you enjoy this book, I recommend the other two Aden novels: Darkfall by Shane Hensley and The Sentinel, the author of which escapes me at the moment.
