Between Worlds is a book about overcoming obstacles and defining what is possible. Mayberry and Marshall go through this fantastic journey, running, plotting, and fighting their way out of anything that comes their way. What it comes down to in the end of the book, though, is that you can't do it alone. Teamwork is a very important aspect of this book. Mayberry, Marshall, and even Aaron can't defeat the evil by themselves. They all need to work together to break the barrier.
In this book, Brittenham develops the characters very well. All of them are unique in their own way. Mayberry is a strong girl who likes to explore and set her own standards of what is possible. She is sarcastic, yet at the same time she is sweet, caring, and determined. Marshall is a boy who dreams of having an awesome life but doesn't hold much hope of it happening. He is courageous, strong, and brave, just not all the time. He has a crush on Mayberry but doesn't want to ruin their friendship, so in that way he is both shy and thoughtful. Aaron is a character who has simply lost hope. He lost hope in survival, family, and life. Mayberry and Marshall come and ignite that flame of spirit once more in his worn body.
I loved how Brittenham wove all of these different characters, plots, and backstories into one story that kept you on your toes and begging for more. I loved the prologue and how it tied into the story, explaining Aaron's grief and hopelessness. This story was well-written, with lots of detail and a great plot line. I thoroughly enjoyed this thrilling tale.
