Too many books, too little time.
Dissolution (Breach, #1.5) - K.I. Lynn description

This is a short story under Nathan’s POV (did I ever told you how I like so much more male pov’s??)
This happens between the time Nathan left Lila, thinking it was the best for her and the end of the book. (That damn end!)

We get to know more about Nathan’s past and understanding why is he so broken and also understanding some of his actions. And God, he is a broken man!
A extremely hot broken man.

A short, fantastic and heartbreaking story :)
