To Sir Phillip, with love (The Bridgertons Book 5) - by Julia Quinn

Eloise Bridgerton is a friendly and extroverted young woman, whose favorite form of communication has always been letters, in which her personality becomes even more captivating.

When a distant cousin dies, she decides to write to the widower and offer her condolences. When surprised by such a kind gesture from a stranger, Sir Phillip decides to return the attention and respond.

Thus, the two begin an intriguing exchange of letters. He soon discovers that Eloise, in addition to being a spinster who never found her perfect match, is a confidant of rare intelligence. And she learns that Sir Phillip is an honorable gentleman who wants to find a wife to help him raise his two orphaned children.

After a few months, one of the letters brings a peculiar proposal: what would Eloise think about spending time with Sir Phillip so that the two of them could get to know each other better and, if they get along, think about getting married? She accepts the invitation, but soon they realize that, in person, they are not quite as they imagined. She is willful and doesn't stop talking, and he is temperamental and rude, with a behavior very different from men in London's high society.

Despite this, in the rare moments when Eloise closes her mouth, Phillip only thinks about kissing her. And every time he smiles, the rest of the world disappears and she just wants to throw herself into his arms. Now the two need to find out if, even with all their imperfections, they were made for each other.
