5 Words: Time-travel, family, grief, hamsters, change. 
 I've just finished this book and I've been left with that weird empty feeling you get when you've just experienced something amazing and know that, somehow, it's going to change you. 
 I don't think that I can put into words how amazing this book is. Reading it was like going on a roller-coaster of emotions. 
 So, this review has taken a fair while to write. And I really liked thinking back, about the story, about what I felt when I read it, about what I liked and didn't like... 
 As much as I loved the experience of reading this book, I also loved the experience of having read the book and thinking back on it. This isn't something that happens often to me. I do think back on what I've read all the time, but I don't think I've ever focused on a single book more unless it was forced on me at school. 
 I loved the exploration of family, it felt like the biggest theme in this book. Because of this crazy time-travel element, the family-unit was all over the place. And it was great. 
 I received a copy of this for free via NetGalley for review purposes.
