I wasn't really sure what to expect from this book, it sounded really good and I wasn't disappointed. I've had a bit of a thing for dystopia for the past year. Add in science fiction and I'm going to probably read the book. I've also read and enjoyed Beautiful Creatures, so to read something by just Margaret was nice.The main protagonist is Dol, she was only a baby on The Day, she knows she's different from others, but doesn't know why. She's captured by the Embassy and they study her and the other three teens that are known as Icon Children. All four have strange abilities, but no one will tell them anything. Their world has basically been taken over by a race of aliens that they have never seen. The aliens are very deadly though, as they showed on The Day. Giving a demonstration of their power, instantly killing everyone in an area. The only hope against them might be the teens and their abilities.Icons is a very amusing read, there were a few places where the story got a bit slow, but I still really enjoyed it. It just took a bit longer to get past those parts. I liked Dol and Ro, how they wanted to help free everyone, even at the cost of their own lives. Tima was a great character, very brave and would do anything for Lucas. Lucas was kind of a jerk though, he was the only one with any sort of privileges. But the characters were likable. The world was easy to imagine, which was good, it helped me get sucked into the story even more.The writing was good, there only being the few slower parts. Overall, I'm really looking forward to the next book in the series.
