“I had a blast journeying through time and across America with Marissa, Clara, and their historic companions in Sean O’Brien’s delightful (or DEEE-lightful!) debut, White House Clubhouse. The story was suspenseful, propulsive, and a lot of fun.

From a former White House speechwriter: a middle grade series following two First Daughters who team up with historical presidential children to save the nation.

Marissa and Clara’s mom is the newly elected president of the United States, and they haven’t experienced much freedom lately. While exploring the White House they discover a hidden tunnel that leads to an underground clubhouse full of antique curiosities, doors heading in all directions—and a mysterious invitation to join the ranks of White House kids. So they sign the pledge.

Suddenly, the lights go out, and Marissa and Clara find themselves at the White House in 1903. There they meet Quentin, Ethel, Archie, and Alice, the irrepressible children of President Theodore Roosevelt. To get back home, Marissa and Clara must team up with the Roosevelt kids “to help the president” and “to make a difference.”

White House Clubhouse is a thrilling and hilarious adventure that takes readers on an action-packed, cross-country railroad trip, back to the dawn of the twentieth century and the larger-than-life president at the country’s helm.
