This was totally worth reading, again. 
 *adding* 
 I am pretty sure Eminem's song Love The Way You Lie ft. Rihanna is a perfect song for this book. Keiran doesn't actually hit Lake, but he is emotionally abusive, doesn't allow her to leave him, goes into a blind rage when other men talk to her and threatens to end her life multiple times. 
 The things you learn about Keiran does help you to understand his.... um... psychopathic ways. It doesn't take away the fact that it is all wrong and heartbreaking sometimes but he DOES get better (ish). 
 *Another book to read with caution. Could possibly cause triggers.
