Hrafnaspark is a short Icelandic young adults' novel by Eysteinn Björnsson.
Appalled at his teacher's right-wing views and callous treatment of Hrafn, Hrafn and a friend break into the school at night while high on ecstasy and vandalise the history classroom (particularly by writing on the walls, hence the novel's title).
He is unwilling to talk to his parents so his left-leaning grandfather invites him to come out and stay at his cottage in the country.
Hrafn decides to return to school; the novel closes with the characters admiring the Northern Lights.
The novel's sympathetic account of Hrafn's left-wing views and rage at society has been read as a response to the 2008–2011 Icelandic financial crisis.
