In the author's note at the end of the book, Wallace reveals that this story came about after researching printmaker Charles Méryon for her master's degree. Once she realized that the Dr. Gachet that treated Méryon for madness was the same one as depicted in the van Gogh portrait of the same name, her writing took a turn to focus on the famous painter. After performing countless hours of research, the author presents her take on van Gogh's final days. Much of the story is constructed using over 900 letters van Gogh and his brother Theo exchanged. Knowing this gives a certain weight and depth to the narrative that might not otherwise be present.

Leaving Van Gogh is told from Dr. Gachet's point of view and takes place in the small town of Auvers in the French countryside. Gachet's wife has passed from tuberculosis, and he lives with his son, daughter, and housekeeper. Van Gogh's brother Theo comes to the doctor to seek his help in caring for the artist after his release from the St. Rémy asylum. Gachet's background is in mental illness, and he's worked in two hospitals. That experience combined with his own skills and appreciation for painting makes him the perfect candidate to care for the ailing van Gogh. The rest of the story focuses on the trials suffered by both doctor and patient. I don't want to give anything away, but if you know anything about van Gogh's life then you know how the story will unfold.

For me, the descriptions of the paintings are where the novel excelled. Many people considered these parts to be too technical, but I found them most appealing. Wallace was definitely able to convey how great an artist van Gogh truly was, from simple portraits to sweeping landscapes. I often found myself online searching for a particular work described, and that gave the overall reading a nice visual layer.

While this was a fascinating look at van Gogh's illness, I wasn't as completely absorbed in the narrative. I enjoyed the story overall, but I felt a little restless at times and lost focus. The writing was a little on the academic side, which is what I think kept me from feeling more connected to the characters. The author didn't take too many liberties with the historical facts, but I wish there had been a little more action as the plot wasn't very meaty. The more I learned about the doctor, the less I cared for him. He comes across as indifferent and is often harsh and uncaring towards his children. A lot of the story focused on Dr. Gachet's life apart from van Gogh, including his time at the mental hospital and his wife's death, and this is where I felt the narrative began to drag. I wish Wallace had kept the focus a little more on Vincent, but that's more of a personal preference.

I haven't read any other accounts of Vincent van Gogh's life, so I can't really say if this would be a decent introduction for someone who knows little. While the plot may not have engrossed me, I do think Leaving Van Gogh was a very insightful look at the debilitating effects of extreme anxiety and mental illness. Wallace does create a haunting portrait of an artistic genius with many inner demons and a lost spirit. An overall sense of melancholy consumes the novel, and it definitely is not an uplifting read. If you are a fan of van Gogh's work or interested in psychology/mental illness then I would recommend reading this, but for anyone else I say skip.
