Clinton, who arrived just before 3 p.m., was greeted with a large ovation. She took photos with dancers who had made a video in her honor before sitting down to sign books.
The book discusses Clinton's failed run for president in 2016. The Democratic nominee lost to Republican Donald Trump. Clinton also signed copies of her new children's book "It Takes A Village."
Nirit Rosenblum, a Chappaqua resident, was there to show her daughters and her son, what a strong woman looks like. Rosenblum said the book has helped her cope with the election.
"I want to thank for her inspiring my daughters," Rosenblum said. "She makes you realize that you can make a difference."
Karen Holdridge, a Chappaqua resident, and Christine Bates said they were excited and nervous to meet Clinton for the first time.
"We need her leadership," Holdridge said. "She means the future on so many levels."
Bates said she was processing everything Clinton has meant to her.
State Sen. George Latimer, the Democratic nominee for Westchester County Executive, was on hand to get his copy of the book signed. He said it's great to have someone like the Clintons as a neighbor.
"She's terrific," Latimer, who worked with Clinton when she was a U.S. senator representing New York. "She's so easygoing and nice.
Not everyone was happy to see Clinton. Two protestors stood across the street wearing "Hillary For Prison" shirts. Amy, who came from New Jersey and declined to give her last name, criticized Clinton for her handling of the Benghazi incident and for receiving debate questions in advance.
"No one is above the law," Amy said. "It's dangerous to let someone like her walk the street."
