Sentinel - Jennifer L. Armentrout AHH! Freaking loved it. Took me forever to finish this series. I kinda lost interest once Seth went all evil and I moved on to books that didn't piss me off. But I am so glad I came back to it because this book was so freaking good. By far my favorite book from the series. I loved seeing Aiden and Alex progress their relationship and make it completely public. Yay for Aiden. And then that ending whoa! I freaking cried like a baby. Kind of embarrassing because I was at work. But if you've read it then you know that it was unavoidable.
