Search - Celebration! (Wagons West, Bk 24)

This is just as good as any of the series and would recommend it. I understand there are follow-up books, which I will want to read, as well.

This is the 24th book in the Wagons West series. The entire country readies for the biggest and most fabulous celebration in its history, one last life-and-death mission will be put in the strong hands of Toby Holt. A secret band of anarchists plan to make the July 4, 1876 Centennial a bloodbath. Unless they are stopped a bomb of terrifying power will destroy libesw and a cherished symbol of our liberty.

Great Series!
