Shadow Games, Book 3 in the Shades of Starlight series by B. L. Dean was excellent. I found this audiobook at my library. Interesting and likable characters, set against the backdrop of the overarching worldbuilding established in the previous books. Book 3 did give off a bit more YA feel to it due to the age of the main characters.
The books in the series are loosely linked by common threads with some shared character interaction between books, but the books stand on their own. Shadow Games centers around Finley “The Flash” McGrath and a Cobalt soldier named Micah Townsend, who grew up together. The story follows Finley and her grav-ball team as they tour through worlds on their way to a World Championship. Fun, political intrigue, espionage, with lots of action. The entire series is appropriate for younger readers.
