I just completed the unabridged audio edition of The Season of Lillian Dawes by Katherine Mosby, and I thoroughly enjoyed it. The language used in the novel is really over the top sophisticated, but since it’s written in the voice of a young privileged American man, the language fits him and his world perfectly.
I also realized that this novel shares many themes with another book I read and enjoyed recently: The Absence of Nectar. Both books have a main character who has obscured his or her identity and history, and both books are a kind of coming-of-age story, though the details differ radically between the two books.
