The Reluctant Journal of Henry K. Larsen is a young adult novel by Canadian author Susin Nielsen, first published in 2012.
That just punched me in the gut; I realized I had never thought about what it would be like for the surviving sibling of someone who committed a horrific crime.
[1] After his older brother takes his dad's gun to school to kill himself and his bully, Henry K. Larsen is thrown into a brand new town and a brand new school in order to escape the anger of his old friends and neighbors.
In this new town, Henry fights to keep knowledge of the "IT" from tainting his new friends' views of him the way it did back home.
Henry begins to understand what it means to grieve for a loved one who has committed suicide, even through your anger.
