What Brothers Do is the true story of two brothers. The first is Captain Patrick Brown, a highly decorated and well respected member of the New York City Fire Department, who was killed in the World Trade Center attacks of 9/11. The second is Michael Brown, a former New York City firefighter and presently a Las Vegas emergency medicine physician. The story takes the reader on Michael's journey back to New York and Ground Zero in the desperate search for his brother and his experiences through post 9/11 New York. Michael is told by all who knew his brother that if anyone could get out of the Towers alive it would be Patrick. As he slowly loses hope of finding his brother alive, Michael changes his focus and determination to fulfilling his brother's last wishes.
In his attempt to honor Patrick, Michael must work through his anger and grief and overcome serious personal challenges. But, he finds friendship and support in an "inner circle" of new friends, reconnects with family members and discovers that Patrick's spirit lives on.
