Gisler was born in Zürich and studied at the Swiss Literature Institute in Biel and at the University of Paris 8.
The novel is told from the niece's perspective; she observes the uncle and circles around him, describing his character and actions and exploring his idiosyncrasies.
Reviewer Roman Bucheli wrote in the NZZ that the bizarre stories in Gisler's debut novel seem to conceal a trauma.
"Only gradually does one realize that a second melody resonates in the hilarity, albeit in a minor key, and that every room in this uncle's house has a false floor.
"[2] D'oncle was extensively reviewed in the francophone media, from Libération to Le Temps.
