Anna runs at the track at Northwestern every morning. One morning she sees a guy smiling and watching her and then when she turns around he is gone. That guy happens to be the new boy at school Bennett. Strange thing is he swears he has never been to Northwestern and wasn't watching her. Anna knows she saw him and swears he recognizes her name but keeps pushing her away. Bennett runs hot and cold but Anna feels very drawn to him. 
 While working in the book store Anna is held at knife point and then Bennett grabs her and then they are in the park. He comes clean that he is really from San Francisco in the year 2012. In Chicago 1995 where they are currently living he has only just been born. Weird! Anna could go visit baby Bennett! As soon as he finds his sister, who he accidentally lost in time, he will have to return. Anna wants all the time with him she can get even if it only is a few weeks. 
 Time travel in this book allows Bennett to choose where he goes, anywhere in the world, anytime during his lifetime. He takes his clothes with him lol and also he can take anyone he wants with him. Anna who has always wanted to travel loves this and I would too! They have romantic dates on beaches on tiny little islands. They spend the night in Italy and then Bennett brings them back to right when they left. The possibilities are endless! Bennett Except that Bennett has been kicked back to his time period when he stays in one place too long and just might be kicked back again. Bennett also has rules he tries to follow and he tries not to change the future too much although he admits he used his powers to become rich! And well who could blame him? 
 Anna wanted Bennett to help change some things when her best friends Emma and Justin have an accident. I loved Justin and felt bad for him at times because I knew he liked Anna but was happy it never turned into a love triangle. They were both really good friends to Anna as she went through some tough times with Bennett. Bennett was really sweet and always wanted to do what was best for Anna. He knows their relationship could leave her broken hearted so I think that is why he was so hot and cold at first. But in the end he was willing to give up a lot to be with Anna and so was she. This was such a sweet romance and reminded me of The Time Traveler's Wife but don't worry it has a much happier ending. :-D 
 "I don't stay...anywhere. I visit. I observe. I leave. I don't ever stay." 
 I'm not sure what I'm supposed to do with this information. Tell him to leave? Tell him to stay? But I don't have time to consider any other alternatives because he scoots closer and brings his hands to my face, and I fall back into the bookcase as he kisses me with this intensity-like he wants me to be here, and if he kisses me just long enough, deeply enough, none of what he just said will actually be true. 
 "I don't think I can go back to a life without you." 
 My face goes blank and I just stare at him. " What are you saying?" 
 "I'm saying...I'm completely in love with you. And...I'm wondering...what if I didn't leave, after all?"
