New Puffin Classics.
Well, new covers and introductions, anyway -- the books themselves, of course, are classics.
You can read some of the new intros over at the Telegraph: Melvin Burgess wrote about Call of the Wild, Meg Rosoff wrote about Black Beauty, Eoin Colfer wrote about Treasure Island and Jonathan Stroud wrote about Just So Stories.
I'm a huge sucker for nice, new clean copies, not to mention matching sets. I want 'em.
