United is the third and final book in the Alienated series. In this installment, the alliance between Earth and L'eihr is being threatened by another alien race. They demand that all humans and L'eihr's return to their homes or they will destroy both civilizations. Of course, Cara and Aelyx are not going to go down without a fight. They are determined to return to the colony and the life they have worked so hard to build together.
This book was action packed as Cara and Aelyx fight off not only another alien race, but also the hybrids from L'eihr, who are working with the enemy to sabotage the alliance. They recruit Cara's brother Troy, Aelyx's sister Elle, and his best friend Serene, but the odds certainly are not in their favor. They have already witnessed the power of their competition and both of their governments have agreed that it is in their best interest to terminate the alliance.
Overall, I loved Aelyx and Cara throughout this series and was happy with how it concluded. There were a few situations in this book that were VERY far fetched, even for fiction. Of course, the end result likely gave readers the warm and fuzzy feeling were likely looking for, but you couldn't help but roll your eyes and think... Seriously? Instead of spending quite so much time on the unrealistic elements, I wish there would have been a larger focus on life on the colony. After the first two books, I was kind of over all of the drama that was keeping Cara and Aelyx apart. I would have enjoyed reading more about how the humans and L'eihrs begin working together and seeing the colony flourish.
Alienated was definitely my favorite book in this series, but they were all very entertaining. I especially enjoyed listening to them on audio. I read the first book, but listened to the final two. The narrator did an AMAZING job with the different character's voices. I especially loved her interpretation of Aelyx's personality.
