Review found here. 
 After reading Just One Year, I feel completely satisfied. It's like the feeling I get after the first serving on Thanksgiving: I feel full but not stuffed. Usually I proceed to continue to stuff my face with deliciousness, but in this case, I'm good. Trilogies are taking over the publishing world, but as they say, there are two sides to every story, and Gayle Forman has mastered the ability to tell both sides in full in only two books. It's miraculous! 
 Just One Year jumps back to That Day. Well, the day after That Day. Willem is in the hospital, and because he has a bit of a head injury, he doesn't remember Allison. When you've only known someone for one day, no matter how life-shattering that day is, no matter how inmportant that person is, if you take a spill that temporarily wipes out your short term memory, you won't remember that person. Of course, Willem does eventually remember Allyson but by the time he escapes the hospital, he's SOL because 1. she's long gone, and 2. he only knows her as Lulu. 
 Now, I know some of you may be incredulous as to the fact that Allison never got around to telling Willem her real name. Let's flash back to High School Mary. She once met a handsome boy from a rival high school's marching band. They met on a Saturday night after a competition and spent hours talking. They never exchanged names. HSM (High School Mary, not High School Musical) was sad. However, fortuitously, their football teams played very next Friday, and they met once more. This time, they exchanged names and then, through a mutual friend, numbers. They then proceeded to date for about two and a half months until it was no longer new and exciting, and the 40-minute distance overcame their mutual feelings of admiration and like-like. *sigh* L'amore. So easily broken by distances between Holland and New York or even just two suburbs. So as you can see, I believe this premise whole-heartedly. 
 What I really like about this duology is that it really explores Allyson and Willem as people, not just their relationship. Most romances describe how the couple gets together. Very few detail the staying-together part. I think that's why books like JOD and JOY and Katie Cotugno's debut How to Love are so exciting. These stories do showcase the getting-together part, but they also show how hard life can make it to stay together. These stories show the ugly side, which is the leaving part, and then the bulk describes how the characters grow, how they morph, and how they attempt to find one another once more. It's lovely. 
 Willem at the beginning of Just One Day is not the same as the Willem at the beginning of Just One Year. He is not the same in the middle either, nor at the end. This novel is so heartbreaking because the boy we met in Allyson's story was a goofy, cocky, charming young man who seems extraordinarily carefree. The boy in Just One Year, in contrast, is broken both body and soul. He's actually got very deep emotional scars in addition to the physical ones he acquired in Paris. Willem is lost in place and in time. He doesn't seem to really fit anywhere, which is why he travels so much. However, he even loses that, and it's like his entire being pales. He becomes someone less. Then, slowly, through the novel, he evolves as he tries to get himself back. He travels through Paris, the Netherlands, Mexico, and India looking for pieces of himself almost more than he's looking for Allyson. 
 When reading Just One Day, I identified with Allyson's story as a girl who was trying to grow into a woman, but I actually went through that part of my life years ago. Now, while reading Just One Year, I found myself identifying more with Willem. A few years ago, I had some traumatic family turbulence, like Willem, and it truly crushed me. It's something I still haven't dealt with entirely, even though I've had time, just as Willem has. I often feel like I don't have a place in this world, that I am unwanted, and those are demons Willem has to face. Every part of me ached in solidarity with each blow Willem is dealt. Gayle is brilliant because she brings these ugly truths to light, but she does it in a kind way. Thus, they don't feel quite so ugly. Just One Day explores the notion that people love differently, and even the people close to us can feel like strangers if we don't accept the way that they love us and they don't accept the way we love them. 
 If you have not read Just One Day or Just One Year, I recommend them highly. Can two people with so little in common find their way back to one another? Or should they just accept one perfect day with a near-stranger and move on? You'll have to find out for yourself. No, seriously. Go read it. Now.
