Wow. 4 steamy stars for sure. Max and Sara are....yeah, wow. Christina Lauren knows how to push the envelope, and that's apparent if you even just flip through Stranger just a bit. What I really love about this book, though, is that Max and Sara are perfect if you want to watch a couple grow intimate emotionally and mentally in addition to all the naughty physical stuff going on. Sara is a wonderful MC, and it's awesome to watch her learn how to stand on her own after getting out of a relationship with a douchey cheating lying politician. Max is a naughty boy for sure, but he's also so sweet and playful and tender. He helps Sara explore some unknown sides of herself, but he does it gently, only giving her what she needs and desires without ever being gross about it.
