Big ideas

Jane Smiley calls Mary Shelley's Frankenstein the first high-concept novel. I think Daniel Defoe's Robinson Crusoe, written a century earlier, might take that title.

What is a high-concept novel? I think of it as a novel with a plot that can be stated in just one or two sentences. Ot it could be said that it is a novel based on an idea. The idea in Frankenstein is about creating life. In Robinson Crusoe, the idea is about a man surviving on a desert island.

Great novels like Adventures of Huckleberry Finn and Moby-Dick could also be described as high-concept novels, although they are of course about much more than a boy and a slave going down the Mississippi River together on a raft and a ship's captain pursuing a great white whale at all costs.

In contrast, such great novels as Middlemarch or Bleak House would be difficult to summarize in a few words. Are they better novels? Not necessarily.

I enjoy novels of both kinds, but I must admit that a high-concept novel is more likely to catch my eye in a bookstore. And it is usually easier to become engrossed in. You have some idea what the story is about before you even start reading because you have read the dust jacket or the back cover of a paperback. You probably know the idea before you open the book.

Some of the best novels have a little of both. Ann Patchett does not normally write high-concept novels, but I think her Tom Lake, reviewed here recently, excels because it has a little of both in it. It is about a woman who finally tells her grown daughters about her long-ago romance with a famous Hollywood actor. But she doesn't tell them everything. That is the high concept that draws reader in. The story itself is more low-concept.

Other recent novels of note similarly have a high concept to get readers interested, then go off in unexpected directions. I am thinking of such novels as Remarkably Bright Creatures by Shelby Van Pelt and The Sacrament by Olaf Olafsson.
