Eden meets new boy Ryan and he is kind of strange. When Eden accidentally brings home a book called My Journey to Eden written by Connor she learns that Ryan is from the future. Ryan knows that Connor gets his heart broken by Eden and then discovers the planet and names it after her. Ryan has to stop that from happening. Most things were well explained. Like I was wondering how that would help since someone else could discover it but Ryan explains that it is only visible about every 800 years. 
 Ryan honestly didn't seem like the best person to send for this important mission to save the world. He spent his time trying to get to know Eden and flirt with her even though he knows Connor is into her. Connor is the one that gets his heart broken and discovers the planet so shouldn't he be pushing Eden towards him?!?! I don't know it seemed kind of ridiculous that someone on such an important mission would immediately make Connor hate him and want nothing to do with him. In the end he wasn't even there and literally did nothing for the mission! He was nice enough but he didn't leave too big of an impression on me. 
 Connor was a sweet guy and I felt bad for him. Eden was naive and even when Ryan told her Connor was into her she still didn't believe it. She did care for him a lot. Everything ends up working out a bit too perfect but I do love a happy ending. While the characters didn't leave a long lasting impression I love time travel and space and the plot otherwise had my attention. I read it in one night and did enjoy myself.

 Connor smiled and leaned toward me. "He's not out of your league. You're beautiful." 
 I couldn't speak. I thought back to what Ryan had said just a few minutes earlier. 
 "So what sort of girls do you like?" I asked, embarrassed. 
 "Are you flirting with me?" he grinned. 
 "Please! You're young enough to be my great-grandson."
