What an excellent story! I can't believe I almost past this story up!What I loved most about this book is the plot. We have twins we are different. The story line flows along with the myth of the seventh son of the seventh son, only this time the son is a twin and the powers they share is AWESOME! I loved how the reader is able to get into the shoes of the both the twins. It is exciting to see how everything is different in Sera or Luke shoes. Especially seeing their powers and how much good they do, I enjoyed their story.There is a love interest but didn't go as planed. But you know what? It's okay. The twins story is much more important. Their powers are part of something larger. Putting each piece of puzzle together, it like watching an amazing painting be painted right in front of your eyes.Now, my only gripe is the pacing. While the story is good, it goes from slow to fast, then slow, then faster, then back to faster to slow. I get that the characters were going through a lot, the pacing for me was giving me whiplash. Still, the plot alone made up for it.Intangible is a great book! It has a plot that is smart and captivating. It delivers engaging action with enjoyment in watching the characters grows. Intangible is the reason why I love to read. Fresh and fantastic, Intangible is awesome!
