Former Speaker Newt Gingrich (R-Ga.) returns to the Capitol Hill neighborhood today to sign copies of his latest work, “Gettysburg: A Novel of the Civil War,” from 12:30 to 2 p.m. at the Trover Shop.

Gingrich co-authored the 463-page historical tome — which imagines a scenario under which the Confederate army triumphs at Gettysburg — with William R. Forstchen.

The Trover Shop is located at 221 Pennsylvania Ave. SE.
