If for no other reason than that you get a whole lot of Hawthorne wrapped up in this collection, it rocks. Most of Hawthorne's writing career was in writing what he called tales and sketches (what we might today just call short stories). Essentially, then, with the diversity of the selection in this collection, you get the full range of Hawthorne's interest and skill. Regardless of whether or not you like Hawthorne I suggest picking up this collection, to have as a reference at least--a reference to the American author that, more than any other skilled American author, wrote about the people and places of this fine country. I hate people who say that Hawthorne is good reading only as a critic of the culture and country of the States; I mean only that he included an incredible amount of American history, culture, and landmarks in his writing.
All the well-known and favorite stories of Hawthorne are here from, I think, all of his publications: Young Goodman Brown, Alice Doane's Appeal, The Ambitious Guest, The Celestial Railroad, Rappacini's Daughter, The Bosom-Serpent, and others. It's a long and great selection of pieces.
The introduction to this collection is worth reading, too. It's an introduction, which are never anything terribly special, but as far as introductions go, Hawthorne deserves an introduction. Hawthorne is so misunderstood, or not understood in any fashion, and under-read that any introduction would suffice as a good one. I don't particularly agree with the introduction that Penguin provides here but, again, it's a fair introduction worth reading.
