The must-have titles for your summer reading list

"Fifty Shades of Grey," "The Help," and "The Girl With the Dragon Tattoo" were all popular summer reads.

So what will be the next big summer read to heat up beaches and pools across the country?

Amazon's Sara Nelson joined "CBS This Morning: Saturday" to discuss the season's hottest books.

One of the books on the list is Hillary Clinton's highly anticipated book, "Hard Choices."

"It's primarily about the last 15 or so years. She already wrote a book called 'Living History,' which was kind of a more traditional memoir from her childhood and on up. It's about the hard choices that she made in life and women need to make in life -- hers specifically were to run for president, to go against Obama and then decide to work with Obama and then choices she obviously made during the time she was secretary of state," said Nelson.

Another must-have book is "Euphoria" by Lily King, which loosely based on the anthropologist Margaret Mead.

"It's about a woman who goes into the jungle with one husband and comes out with two," said Nelson.

One sleeper hit to make the list is Cristina Henriquez's "The Book of Unknown Americans."

"This is a book that sort of snuck up on us at Amazon, but it's a novel told in many voices of Latin American people and South and Central Americans who come in this country and live in one apartment building in Delaware. The love affairs and various things that go on - but really about what it means to be an American and what it means to have come here and what it cost them and what you get," Nelson said.

For those into environmental issues, Nelson recommends Joshua Horwitz's "War of the Whales."

"It's sort of an environmental whodunit and there a lot of experiments that the government is doing, that the navy is doing in the water that seems to be affecting sea life. There are no bad guys but there are sort of good guys and other people who think they're good guys and how what they're doing is going to affect our world," she said.

In the young adult category, "We Were Liars," by E. Lockhart is sure to keep teens' attention spans.

"It's about an ordinarily messed up family, a wealthy family that summers in a place like Nantucket and secrets that come up during course of that summer," Nelson said.
