4.5 stars 
 Four years after Drew and Fable, Owen is a 19 year old college student, following in Drew's football star footsteps. But his grades have been slipping, and after a meeting with his coach, counselor, Drew and Fable, he is required to meet with a tutor to raise his failing grades. 
 His tutor is shy, bookish Chelsea. A 19 year old junior, Chelsea works two jobs and carries a heavy class load, but doesn't take time to socialize except with her roommate Kari. 
 Owen was always one of those characters that you couldn't help loving when we saw him in Drew and Fable's books. As a child he had to grow up fast. But now that he's all grown up, he is still influenced by the events of his adolescence. So many times in this book, his own doubt makes him make decisions that get him in trouble. 
 ...I'm starting to realize I want what Fable and Drew have. I know I'm young, but sh**, they were young too when they first met and fell in love. And look at them. Years later, they still act like they're totally gone over each other. 
 Chelsea was so different from anyone Owen had ever been around. Sweet, shy, and awkward around Owen, she was not used to being attracted to someone. Never having been in a relationship before, she is just as uncomfortable with the unfamiliar territory as Owen was. It was nice to read about a girl who was just as unfamiliar with relationships as the guy she was interested in. 
 Together, Chelsea and Owen were a perfect match. They had great chemistry. Something about Chelsea caught Owen's attention where other girls never had. And she could tell Owen was more than the jock persona that he wore in public. I liked that Chelsea called Owen on his mistakes from very early on, from their first meeting. She may have been inexperienced, but that doesn't mean she didn't know what she wanted or needed and have the backbone to stick up for herself. 
 "I'd rather not know what I'm doing with you, Owen, than have everything plotted out for the rest of my life with someone else." 
 I loved seeing the interaction between Fable and Owen now that they are both adults. Owen wants to protect Fable, while she still wants to take care of him. But their mom? Ooooh, she made me mad. Again. Her influence is a big part of what Owen has to overcome. Years of treating Owen more like a buddy than a son have left him questioning a lot about himself. 
 Owen and Chelsea's friends play a good role in the story line. I love when friends come in at the perfect moment, and it happens several times in Four Years Later. There's Owen's friends, Des and Wade. Des, I could do without. As Owen's drug dealer and house crasher, Des always felt a little off to me. But even though I didn't like him, I wondered what his story was. And then there's Wade. Wade has been best friends with Drew since they were kids. We finally get to meet him on the page here. I thought I didn't like him, until he was the best friend Owen could ask for. Wade knows Owen, maybe better than Owen knows himself and he showed it when Owen needed it most. Chelsea doesn't have many girlfriends, but her roommate Kari is constantly trying to get her out of her comfort zone, and there is a text conversation that had me laughing and grinning, in addition to her attempts at getting Chelsea to relax and loosen up a little. 
 Four Years Later was fun, full of great characters, interesting plot twists, good friends, good family, good times. It makes me sad to think this is the last of the One Week Girlfriend books, but it was a perfect addition to complete the series.
