For many Americans, summer is the season of backyard barbecues, bonfires at the beach and unforgettable family vacations.

But for the Clintons, never ones to be ordinary, this summer has been anything but.

Since the release of her memoir, " Hard Choices," in early June, Hillary Clinton has been on an epic nationwide book tour and press blitz. Over the past 58 days, she has made more than 77 appearances, including book signings, speaking engagements and media interviews, across roughly 15 states and four foreign countries.

Her husband, former President Bill Clinton, has also kept his own rigorously packed schedule, which has included trips on behalf of the Bill, Hillary and Chelsea Clinton Foundation to Europe, Southeast Asia and Australia.

This past weekend, the Clintons took off to vacation in Amagansett, New York, a beach town on Long Island - meaning perhaps the most energetic duo in politics, soon to be grandparents, and possibly the next couple to call the White House their home, finally carved out time to relax, unplug, put an end to the book tour and retreat back into life as private citizens.

Right?

Wrong.

Not even 48 hours into their vacation, Bill Clinton trotted off to Washington, D.C., to moderate the opening session today of a business forum at the U.S.-Africa Leaders Summit hosted by President Obama.

Then, Wednesday, the former president will head to Kentucky for not one, but two, campaign events for Democratic U.S. Senate candidate Alison Lundergan Grimes.

Meanwhile, back on Long Island, Hillary Clinton has scheduled her own public appearance for the same day: a book signing for her memoir in Huntington, New York.

In addition, both the Clintons are expected to attend a fundraiser Saturday evening for the Clinton Foundation at the sprawling home of New York philanthropists Joan and George Hornig. Tickets for the event, according to the New York Times, cost tens of thousands of dollars each.

That's not all. Next weekend, Hillary Clinton has scheduled two more book signing events: one in East Hampton and the other at a bookstore in Martha's Vineyard. While there, the former secretary of state will overlap with the Obamas, who will be vacationing in the Vineyard at the same time. It is unclear however, whether they have any plans to meet up.

Later in the month, Hillary Clinton has a keynote speech scheduled for a tech company in San Francisco, in September is the annual Clinton Foundation meeting in New York, and through the fall both Clintons will likely campaign for midterm candidates before their daughter gives birth to their first grandchild. After that, Hillary Clinton may decide to run for president.

And then, well, there isn't any foreseeable downtime.
