I enjoyed reading this book quite a lot. At first I had my doubts about it since it sounded very predictable and stuff but once I started reading it, I knew that it was going to be a great read. 
 Right off the bat, the first few chapters had me tearing up. It was sad to read about Quinn's boyfriend, Trent, dying and how much his death affected her. Not only did she have to life with the fact that he died without any warning, by a car accident, but she also didn't even get a chance to say goodbye or be with him one last time. Everything was sudden for her, and after losing her boyfriend and best friend, it was hard for her to get back to her life because she didn't want to, she struggled with getting over the fact that he's gone and she stayed in a haze all through the rest of her junior and senior year, not even bothering to do anything like apply to colleges or even hang out with her friends. 
 With Trent's death, she learned that his organs were donated, and so she decided to write letters to the people that were recipients of Trent's donated organs, like his eyes and lungs and kidneys. She met with all of them and talked to them, seeing how their lives were better because of Trent. Trent's family and Quinn got some closure from speaking with them but there was one person that didn't write back to Quinn or made any attempt of contact at all. 
 And so Quinn moped around the house for 400 days until one day she decided that she was going to see the recipient of Trent's heart, Colton Thomas, who she did extensive research online to figure out his identity, and after seeking him out, she only wanted to see him not talk to him but things don't go exactly as planned. She ended accidentally talking to him and then after hitting his blue Volkswagen bus, they start hanging out and getting to know each other better. 
 I actually liked seeing their relationship build into friendship and then more. It was interesting seeing the parallels to Trent, they were both athletic, they both said "Hey, wait" to her while she was running, and they both gave her a sunflower, oh and they both kissed her in water. Apart from that, while it might have seemed like a little bit of instalove or some unseen force, they were attracted to each other from the start. While it could have been from looks and circumstances surrounding them, I was glad to see it grow into something more. They each helped each other face the day and live their lives to the fullest. They kept secrets from each, and while I admit Quinn keeping who she was a secret could have been handled better and they could have avoided all the drama, I think it was necessary for them to get to fall in love with each other first, without Colton telling Quinn about his heart transplant and her pretending she didn't know anything. Colton didn't want to be seen in a different light and Quinn didn't want to be hated or risk losing Colton. In the end, everything worked out for them. 
 I'll admit it got a little bit annoying how she didn't let go of Trent. She didn't move on from his death easily and being reminded of how much she missed him every few pages was annoying and made me want to give Quinn one of those "tough luck" attitudes her Grandma was always talking about, but I also understood where Quinn was coming from- her best friend turned boyfriend of 3 years, of which she had a lot of memories and whom she was in love with, died and quite literally left her heart broken. It was safe to say that it wasn't only Colton's heart that was mended, Quinn also found the strength and happiness to move on and be happy again, this time with Colton. 
 I definitely liked all the quotes about the heart at the start of each chapter, and all the times Colton mentioned Emerson and living your life to the fullest, to live in the now and enjoy the small victories. I think we can all take a page from Colton's book. I definitely recommend this for others to read because it was a quick and easy read, not to mention sweet and meaningful.
