2.5 stars. It took me 5 days to finish El Diablo. I put it down to read other books because I wasn't all that into it. The first half of the book was meh. I struggled with all of the years when Alejandro was a teenager because he was behaving and speaking way older than his years and it didn't come off as believable. Even though he was forced to grow up way too soon and engage in a rough lifestyle, it was still over the top. I enjoyed a lot of it from 60% or so until close to the end. Mostly the romance between Alejandro and Lexi. The ending was fine. I'm happy with the happy ending and the way things came together but it wasn't anything special in my eyes. I guess I just didn't really connect with the characters enough. Also, there were several side stories and supporting characters that pretty much just fizzled out and dropped off. Leo and Briggs especially. I did some skimming during filler parts that didn't hold my interest but I know I didn't miss anything important to the storyline. Overall, I thought this book was just okay. It had some really good parts but I didn't think it was consistent. 
 A lot of people really loved this book and I received many recommendations to read it so I think it was a case of it's not you, it's me.
