Fast paced and exciting, probably the best of all three. I really liked the growth of the characters and there were some nice little surprises as well.

I received an advance reader copy in exchange for a fair review.

The final book in the GEOs trilogy went out with a bang! I really loved this book! It was probably my favorite of all three. The pacing was great and there was a lot of action as well. There was the most obvious character development in this book and I just found it to be the most entertaining in general. It was a page turner for me and I couldn't wait to find out what happened next. Tylia was quite literally all over the place, with the geos, on the surface and in the greens, back and forth, through most of the book, so it seemed pretty long (in a good way!), even though I don't think it was based on how quickly I read it. Like Ramona's other books, I love the characters, plot and writing, and I am sad to see this series come to an end. However, the ending was very rewarding!
