Hey great thread Meg!
I will contribute to the list with some Argentinean writers that I like.
Let's see...the list could be endless, but I'll be brief -and subjective.
I could start with Julio Cortázar, one of the best Argentinean writers. If you have not had the indescribable pleasure of unveiling the fantastic worlds that Cortázar has built with his words, please wait no more. For non Spanish speakers I heard Gregory Rabassa's translation into English of "Rayuela" is very good.
Why not continue with one of my favorites Oliverio Girondo, I could never get tired of reading his magic poetry in verse and prose.
Then there's the rebel son of Argentinean literature: Roberto Arlt -genius.
And I don't want to forget of Manuel Puig with his delicious games of intertextualities.
More visceral and contemporary, I like Alberto Laiseca, reading one of his books it's quite an experience.
Also, of the still alive, Federico Andahazi, Rodrigo Fresán and why not Alejandro Dolina.
Women: Silvina Ocampo and Alfonsina Storni.
I don't want to end this without mentioning Jorge Luis Borges, most surely the best writer from these lands, but if you've read the ones I mentioned above, you will see why I can't say he is one of my favorites. Probably too good for me
I'm leaving many out -and maybe my list is too obvious too- but I'm sure other Argentinean students can add to this.
I'm eager to read about literature from other countries too, so please share with us!
