Two survivors of the Boston Marathon bombing were at Fairfield University Friday to give a reading of their new children's book.

Jessica Kensky and Patrick Downes gave the crowd a reading of their book "Rescue and Jessica: A Life-Changing Friendship." It tells the story of Kensky's struggle after losing both legs in the 2013 bombing and how her service dog Rescue helped her get back on her feet. Downes lost one of his legs.

Hundreds of kids showed up to the Quick Center for the Arts to hear the story of perseverance and friendship from the husband-and-wife team.

Kensky says Rescue was a crucial part of her recovery.

"It was such a profound time of loss and I was in such a deep depression that he really lifted us both out of that," she says. "I can't imagine going through this without him in my life."

The book is available at the Fairfield University bookstore and other retailers nationwide.
