Merrin and Elias are on the run and they're being hunted. They're looking for a safe place that will give them the opportunity to figure out what's going on in their lives...what the Biotech Hub was trying to do to them and others and what they should do next. As you can imagine, this story is filled with twists and turns and unexpected situations. But, at the same time, it focuses on relationships and the importance of family and friends, making it a well-rounded book. 
 This is one of those books that's tough to review without giving away anything. So much happens in this story that I'd love to tell you more than I'm about to...but, I think you should read this series for yourselves, so I'm going to do my best not to spoil it for you. 
 The first book, One, was in Merrin's point of view so I was surprised to have this part of the story be told in Elias' voice. However, it is a great change - one that provided a different point of view and a new understanding of the situation. Plus, we get to know more about Elias which is a good thing. Seeing this world from his point of view explains some of his actions in the first book...we're able to understand his emotions and intentions and it helps us realize that everything that's happened has affected him very deeply. Elias is a good person through and through and all he wants is to protect his family and Merrin...and to live a simple quiet life. I'm not sure I understood that fully in the first book but it's crystal clear here. 
 Merrin, on the other hand, is more focused on finding the solutions to their problems and, of course, super powers. This causes our boy Elias some stress and adds some angst in their relationship making it feel more realistic, even in this fantasy story. Some of the secondary characters from the first book find themselves hooked up with Elias and Merrin again and help our heroes try to solve these mysteries and battle the bad guys. Also, a few new characters with amazing super powers are added. My favorite is probably Hayley who is snarky and sassy and smart. 
 This is the type of story that keeps you on your toes, provides you with characters that you grow to care about and gives you bad guys who are truly bad. It'll keep you reading and, with so may great secondary characters to like, you'll enjoy exploring this great and creative world!
