The entire series is written so well, what with the loveable written main characters that actually have interesting and good personalities unlike some other books, but also the mixture of romance love triangle, and a very very good mystery.
Honestly my favorite character was either Nash or Xander, both hilarious and kind characters love how protective Nash is. It's safe to say I'm slightly obsessed, and have become attached to the book heavily. 110% recommend, try read the entire series too because it's honestly so interesting but you probably should read it all because book 1 ends "unfinished" with them needing to solve unsolved mysteries. So reading the entire trilogy is the best idea.
Cannot express my love for the writing and book enough, please go read it.
