The moment Javier was first introduced in Sins & Needles, I was automatically intrigued. OES tells the story of Ellie (known as Eden) & Javier, it's essentially the prequel to Sins & Needles. Right from the get-go you can feel the connection between Ellie & Javier, something I thought that was lacking with Camden. I really liked this better than S&N. All I know is that, Cam better up his game in the next book cuz Javier is winning me over.
