In short: Unfortunately, Icons by Margaret Stohl failed to impress me with its standard and slow paced plot, its botched scientific explanation, and its flat characters. 
 I struggled with Icons, which was frustrating because I could see the potential in the concept. Aliens (or "Lords") invade Earth and teens with special powers (the "Icon children") help protect humanity. It was a premise that I should have found interesting and gripping, but instead I found that I just couldn't get into the story. I can't decide if it was just me and the mood I was in when I read Icons or if my issues with it are legitimate concerns. I kind of think it's a bit of both. 
 I made the false assumption that we were going to see aliens in this alien invasion novel. But we never see them and we are given such limited information about the Lords that the alien invasion aspect of Icons might as well not have been included at all. As such, without the inclusion of any sci fi interest, Icons was a pretty standard dystopian. Not a bad one certainly, but I've read so many of them at this point that Icons fails to leave an impression in the face of much better dystopian fiction, unfortunately. 
 Like I said, the Icons' concept has a lot of potential on the surface. There are four Icon children and each of them is the embodiment of one emotion - Sorrow, Rage, Love, and Fear - and they are thought to be the key to destroying the Icons that control humanity, as having these heightened emotions somehow gives them special powers. Now, I like a unique concept as much as anyone, but my problem with this one is that I needed a valid explanation for how it works and I never got one. Margaret Stohl only attempts a vague and nonsensical scientific explanation that did the concept no favours. I would have preferred she had called it what it was - just plain magic - instead of attempting a half-hearted and botched scientific explanation. 
 With the plot of Icons falling to pieces, one would hope that the characterization would make up for it, but unfortunately, I had just as big a problem with that as I did with the plot and concept. I'm not sure if it was because the Icon children were each the embodiment of one emotion only, but this led to some very flat and static characters. Dol, Icons' protagonist, is likeable enough, but her character was pretty unmemorable and bland, which thus made it hard to relate to her. There is also a love triangle here and it is both unnecessary and lacking in chemistry on both sides. 
 Overall, Icons failed to impress me with its standard and slow paced plot that couldn't keep my interest, its botched scientific explanation for the concept behind the novel, the flat and static characters, and its unnecessary love triangle. I am quite sad about this because I do quite like Margaret Stohl as a person and author and I love her humour. I still maintain the she has great ideas and is a talented writer as I did enjoy the idea and writing for Icons. But I just couldn't get into it. I do think that some of my issues with Icons were quite personal though, so I feel like lots of people will - and have - like it considerably more than I did.
