Too Late by Colleen Hoover

Sloan and Asa are a couple where it seems, he always needs sex. Sloan is trapped and has to rely on him and his money to help her but he sells drugs and has too many parties for her liking but he pays for her brother's special care.

In university Spanish class Carter and Sloan meet and go on a date but Asa has a tracker on Sloane unknown to her whilst sleeps with any girl uses them and calls them a whore in his mind after his father issues we learn about.

Asa is overprotective of Sloan being his property and is particular about the company he keeps. So much so he doesn't see Carter and Sloan becoming close as she grows more scared of Asa and his behaviour.

Then there's a huge twist ahead with Luke and Ryan who are undercover cops, Asa is onto them and plays on schizophrenia like his parents doing many pills and loving his coconut cake.

There is a shooting, very tense all through the last few chapters and two epilogues to finish an amazing book!
