Gump & Co? Read it many years ago. The actual story itself seemed a bit subdued compared to the original. However, I'll immediately recommend it for the way novel Forrest refers to the Forrest Gump movie infiltrating and messing up his life, even meeting Tom Hanks at one point. Wonderful approach by Groom that I never would have expected.

You might also want to check out The Hundred Year Old Man Who Climbed Out a Window and Disappeared by Jonas Jonasson. Only read the first one (there's a sequel), but it's possibly even more satisfying than Forrest Gump. Lots of fun.
