The first of her novels, Northanger Abbey is Austen's most youthful and optimistic. It is centered on the loves and friendships of Catherine Morland, an endearing young girl extremely fond of novel-reading who, during an eventful season in Bath, meets the sophisticated Henry and Eleanor Tiley who invite her to stay at their father's mysterious house, Northanger Abbey. There Catherine runs into dangers, imaginary and real, and learns how to tell the difference between books and real life, false friends and true.
