One in the Chamber - Peguero, Robin

From a former U.S. House spokesman and Senate speechwriter, a group of junior staffers working on Capitol Hill find themselves in the middle of a political standoff in this satirical novel.
Iowa Farm boy Cameron Leann is new to Washington, D.C., joining a group of employees working for a powerful cohort of U.S. Senators known as The Gang of Six. All of Cam's new colleagues have one thing in common: they hate their bosses.
When a bombshell revelation threatens to sink the President's Supreme Court pick, the Gang of Six fractures, pitting senator against senator in a confirmation battle for the ages. Alliances shift with the wind. Everyone is lying to everyone.
Cam and his friends are caught up in the midst of everything...and on Election Night, one senator will end up dead.
