Alex believes herself to be invisible, living in the shadow of her best friend Seth. Seth is athletic and sociable, and is in the closet that however, doesn't stop Alex from being in love with him. Still, she doesn't feel that she needs anyone else in her life. Of course, that all changes with Seth's secret is let out of the bag. Alex finds that she isn't as invisible as she thinks she is, and that maybe he isn't the only person she needs. I didn't think I was going to read this so quickly. Once I started it, I tried to put my kindle down as rarely as possible. I liked the pace, usually I feel like some YA contemporary kind of drags and I didn't get that with I Loved You First. It kept me interested the whole time.I also have to say that I really liked Alex for the most part. I'm a wall flower by choice myself. However, one thing I couldn't figure out, was why she loved Seth. Honestly, right from the beginning he seemed like a jerk to me. He seemed to take advantage of her every chance he got (ex: dragging her to parties and dates), just because she loved him and was her best friend.I would give this book a 3.5/5. For a quick read it was enjoyable, I was, however, slightly disappointed with it. I feel like the characters might have been missing something. I also don't think that Seth really went through much, though he gave up so easily.I was asked by the author to review this.
