Let me start of by saying that I absolutely loved this sequel to Alienated! And that I'm sad to hear that it's only been a 2 book deal, and while it does end without too much a cliffhanger and it does have a "satisfying" ending, it does make the reader want more books in the series! I guess we all have become used to books series being around 7 books long for some, and others being a trilogy. Either way, as long as there are novellas around, I guess we will be pleased. Now, there is a slight chance of there being a third book in the series, so fingers crossed! 
 Now, this book was well done like the first one, and dare I say, even better than Alienated? Why, yes, I do. It was so much better. Don't get me wrong, I liked Alienated and everything but Invaded was just a really good sequel. It had twists and turns and lots of suspense that had my brain going in circles trying to figure out what was going on and who were the bad guys. I liked that this time, it was Cara's turn to go to Aelyx's world and learn about his culture and the people there. 
 On the other hand, I liked that there wasn't a love triangle involved at all! Seeing as how I hate love triangles, I was a little skeptical about reading this book especially seeing as how Jaxen showed his interest in Cara in the ending of Alienated, but boy was I glad when Cara and Aelyx only cared about each other and were not interested in anyone else! Because of that, it was nice to see how they each handled being apart from each other, and then being reunited after months of being apart. Of course, because of certain issues with human basic rights and the colony, Cara decides that maybe she doesn't want to go live in the colony after all and they break up. I admit that I was tiny bit sad about that, but for some reason I wasn't devastated. I guess since there was still pages left in the book, I was convinced everything was going to work for them, and it did. 
 On another note, the romance overall in this book was awesome, if a bit heartbreaking. Syrine finally got the chance to get over Eron, whom she had an unrequited love because he loved Aelyx's sister and the was murdered, and she fell in love with David. I have mixed feelings on the whole David front, because while his interactions with Syrine where awesome and sweet and hilarious, I can't over the fact that he betrayed them, but I sort of soften when I remember what happened to him and Syrine. Not to spoil too much but there will be happy and sad tears being shed. 
 It was interesting to get more insight into the L'eihrs and their world, so I was glad it took place in their planet, and we get into the whole attempt coup and evil villains, and bam it makes for an interesting story. I didn't want to put the book down at all because I was glad to be back to this world and the characters in it. Throughout the emotional rollercoaster of Cara being blamed for pranks and crimes, and all the attempted murders of Aelyx, the journey was a good one and I hope, fingers crossed!, there's a third book in the future!
