2.5/5. 
 I didn't hate this book, but it felt a little lackluster. 
 Kenji is my current favorite character and honestly the only character I like at the moment. The romance plot was annoyyyiiiingg, it wasn't quite instalove, but it was pretty much instalove. 
 Generally with short books, I'm expecting them to be pretty action packed, but the action scenes weren't super riveting in Shatter Me. I know it's a debut, so I'm sure Mafi gets better with more practice, but in this book, I was honestly only half paying attention to the book half the time because of how unexciting it was. 
 Also I know people love Warner and hate Adam and that I'll figure out why later on, but I don't know if Warner can redeem himself in my eyes from the toddler scene. Also Adam was pretty boring and a little annoying, so I'm sure it won't be hard for him to get on my bad side. 
 The writing was pretty hit or miss, and I definitely cringed at a few of the sentences. But I think this is also just because it's a debut book. Maggie Stiefvater's writing in The Raven Cycle is really beautiful to me, but I've read a few excerpts of Shiver and it's pretty purple prose-y. I think it just takes a while for author's with a more flowery voice to grow into it. 
 I'll definitely continue because (view spoiler)[ the ending gave me X-Men vibes and (hide spoiler)] I've heard this series vastly improves as it goes on.
