There are a lot of chase scenes, and lots of suspense. There are also twists and turns, and it's hard to figure out who is on Cassie's side and who isn't. She also has trouble figuring out exactly what her relationship with Asher is-- does he stick around because he has to, or because he likes her?
The ending of this book makes it very clear that there is at least one book necessary to figure things out, and I'm sure it will be as action packed and adventurous as this one. Return Fire and the Moving Target series is a great choice for readers who like mythology, travel, and plenty of explosions! Hand to readers of Gibbs' Spy School, Carter's Gallagher Girls series, and McMann's Unwanteds.
