I have to admit, I didn't read the Lux series, but from the First Impression I didn't feel like that was a problem. The story was able to build the world and characters in a way that explained the plot and didn't make me feel totally lost. I'm excited to see where things are going to continue to progress! Aliens are something a little more new in the YA world and I'm thrilled that Jennifer L. Armentrout is doing that so successfully.
