Michael Connelly said this quote

All his life Harry Bosch believed he had a mission. And to carry out that mission he needed to be bulletproof. He needed to build himself and his life so that he was invulnerable, so that nothing and no one could ever get to him. All of that changed on the day he was introduced to the daughter he didn’t know he had. In that moment he knew he was both saved and lost. He would be forever connected to the world in the way only a father knew.- Nine Dragons by Michael Connelly
