A week before the annual Easter Egg Roll on the White House lawn, First Kids Cammie and Tessa, daughters of the first female president, and their cousin Nate attend the opening of a new dinosaur exhibit at the National Museum of Natural History. As the prize display, a seventy-million-year-old dinosaur egg is being presented, it cracks, and a tiny hatchling emerges! This is no dinosaur, but an ostrich. But where is the real dinosaur egg? The First Kids and, of course, First Dog Hooligan are on a new case as their investigation leads them behind the scenes at the museum, to an ostrich farm, and to a foreign embassy. This is the fifth book in the First Kids Mystery series.
