I like that I can pick up any Carol Goodman novel and have my expectations met. Her The Drowning Tree is a classic example; it's peppered with water imagery, poetry, an "other" woman and twists.
The book has a dual story, following a modern-day woman, Juno, whose husband was put away for insanity. After something horrible happens to Juno's best friend, Christine--who also was a good friend of her insane husband--new twists and turns reveal a connection to the past. Juno's life begins to reflect the story of two Victorian women who may also be connected to Christine. It's an interesting contrast between the two eras and stories.
I like how Goodman examines a theme in her works. This time, the theme was on art and madness. Can a deep obsession with art--and creating art--drive you to madness? What is the relationship between the two?
Goodman is smart and it shows it in her writing. I feel more intelligent just reading her work.
