Edwina Booth has just reached her 18th birthday and is beginning to experience the benefits of adulthood. For one, her father, the famous American Shakespearian actor Edwin Booth, is finally allowing her to see him in his title role in King Lear. For another, she's being invited to all sorts of social outings and parties for young people. The advantage of the latter is obvious - in Edwina's practical mind, she already has plans to find a husband (an artist, preferably) who she can marry and support. In fact, it seems her entire life is planned out precisely the way she wants it. But meanwhile her stepmother's illness worsens, her father has to keep up with his life as an actor, and there's always The Subject that threatens to interfere with the lives of the Booth family. You see, Edwina is the niece of John Wilkes Booth, the man who assassinated President Lincoln.
