It is such an amazing, short read that gets you thinking. 
 It's under 200 pages and I honestly wouldn't change it. I think it being a full sized standalone instead of a short paged series works brilliantly for this story. 
 Charlie and Silas are amazing and I love how we get to learn everything new with them. Not everything is straight forward and happy go lucky. There are issues other then their memory loss that has you intrigued and trying to figure out if its connected. 
 Such a simple idea made into something outstanding! I didn't expect to enjoy it as much as I did. 
 I can't wait for part 2!
