Excellent! I really enjoyed this novel, and I'm glad I finally got around to reading it. A really interesting concept, having an 'echo', who is raised to be your understudy, and will step into your life, should you ever die. 
 I would honestly give this 4.5 stars- I liked the characters, and the plot, but the last third of the book felt very rushed. I saw that it was originally written to have a sequel, but now is a standalone, which explains the unfinished feel of the story. 
 The characters were pretty good- even though some of them were a little flat, they're presented in a way that makes their actions (or lack thereof) understandable. 
 The best part of the story was Lekha. She's a side character, but she can definitely steal the show. She's hilarious, quirky, and I wish I could be friends with her!
