Pro-democracy activist Luc Nkulula, from the Democratic Republic of Congo, died in a fire at his home in June.
Nkulula, a fearless campaigner, had to put up with regular beatings and arrests, and his friends suspect the fire was started deliberately – an investigation blamed a faulty solar panel.
He helped found La Lucha, a group of young people fighting for a more democratic country.
But the authorities seem to stand in their way at every turn.
