There is always something magical about South-American writers. They seem not to have forgotten how to write a novel – that it takes a story, then some chuzpa telling it, and a pinch of mystique in the presentation. All those things together make a compelling world in which you can get lost no matter where your physical self is.
The young Marquez had the gift, as the gigantic Isabel Allende. When you read their stories, they sound a lot alike: full of characters that are always described with humor in the mind; redolent with thoughtful and thoroughly researched descriptions of worlds the author does not know; filled with tension that finds its release on time, and slowdowns that never last too long.
Not many authors can do that well. Tolkien comes to mind, who could be the honorary patron of these Spanish writers. Capote would be the closest I can associate here in the States. Maybe Michener on a good day.
