Oskar Luts was the most prominent prose writer of the early Estonian literature, who is still widely read today, especially his lyrical school novel Kevade (Spring). Anton Hansen Tammsaare's social epic and psychological realist pentalogy Truth and Justice captured the evolution of Estonian society from a peasant community to an independent nation. In modern times, Jaan Kross and Jaan Kaplinski are Estonia's best known and most translated writers. Among the most popular writers of the late 20th and early 21st centuries are Tõnu Õnnepalu and Andrus Kivirähk, who uses elements of Estonian folklore and mythology, deforming them into absurd and grotesque.
