I started off very confused. The new concepts I was introduced to like the Outside threw me off. When the author suddenly called someone "Perry", I was all, "who the heck is this?!"... then I realised the chapters' titles were the names of character the POV was in. It was then I actually read the summary for the book--then I understood! I wasn't sure if I was going to like the book; I didn't want just another dystopian. Well, this book is a dystopian, but I really liked it :) 
 Aria has been really sheltered her life--a Dweller. She has a device called a SmartEye (attaches to your eye) that lets her experience the Realms, which is like virtual life that replicates real life. Her mother, a genetics scientist, has been taken to somewhere called the Bliss. They usually communicate through their SmartEyes, but recently, their link has been down. Aria's worried, so she tries to persuade Soren, the head of securtiy's son. This is where the book starts, and I don't want to spoil the rest of it for you! 
 Peregrine, or Perry, is a Savage--an Outsider. Perry is very special, as he is Twice Marked. What does that mean? Well, I'm a little confused on the whole Seer vs Scire thing, but I know that he has two Senses (senses that are really enhanced): one allows him to see in the dark and the other gives him such a strong sense of smell that he can sense emotions/tempers. He lives with a tribe called the Tides, where his brother, Vale, is the Blood Lord (the title of the chief). Vale's son, Talon admires his uncle (that would be Perry) more than his father. In fact, Talon and Perry have "rendered"; they have a bond allowing them to sense each other (I'm a little shaky on what exactly it is as well). Talon's sick with the same disease that killed his mother. So, Perry sees it as his duty to help Talon, which would mean breaking into the Dweller's. 
 Then they meet ;D 
 I dunno why I used so many commas!!! And hopefully I'll understand more when the next book comes out
