**I received this book free from the author in exchange for an honest review.**
I really enjoyed this book. In the first few pages, I wasn't entirely sure what was going on, but then, as we learned more about auras and the colors and their meanings, and what Cal could do with them, I was intrigued. So intrigued, in fact, that I couldn't put the book down, and finished it in one sitting.
I really liked that The Athena Effect was a self-contained book, which made it much easier to devour in one sitting, since I knew I didn't have to wait for the second book in a trilogy to be released (or immediately move on to the rest of the series).
I thought the idea was creative, and it's not one I've seen before. I also liked that science played some role here and Cal's unique power wasn't inexplicable. Too often, characters are given powers that seem cool, but that we're just told to accept as being possible. I liked that here there was some kind of explanation.
I did think having two characters named Cal was a bit much. After they started using their full names, it was easier, but there was a small segment where I wasn't sure which Cal the author referred to, especially since the POV switched back and forth with no warning. That's my other complaint. I don't mind multiple POVs in a story, but they should be in their own little sections. Switching back and forth between paragraphs or within them is confusing, and I'm not sure having both POVs that way really added anything to the story.
All in all, this was a great read, and I'd recommend it to anyone who enjoys paranormal/fantasy young adult books.
