[1] She was part of the Barcelona literary scene of the 1970s and 1980s, maintaining friendships with such writers as Juan Goytisolo, Carlos Fuentes, Josep María Castellet or Enrique Vila-Matas.

[4] Amat's literary work is often complex in form and focused on the processes of reading and writing, frequently employing metafiction.

[2] Her body of work includes the novel Todos somos Kafka, which both reflects on the literary tradition and its own structure;[2] it was called "magnificent" by Carlos Fuentes in El País.

[6] Her books have been translated to Arabic, English, French, Italian, Hungarian, Portuguese, Romanian, Swedish,[3] Czech[7] and Polish.

She has written a theatre play called Pat's Room (1997)[1] and a novel Amor i guerra about the assassination of Leon Trotsky by Ramón Mercader, with whom she is distantly related from the mother's side.
