Pineapple Express is Evelyn Lau's eighth collection of poetry. The collection is rooted in the mind and its disorders. Depression, anxiety, and obsessive thinking have been explored widely in fiction and non-fiction, much less so in poetry. "Pineapple Express" explores moods, medications and side effects, capturing the flatness of depression while making the language sing. It also explores the notion of mid-life, in all its manifestations: physical changes, psychological upheaval, the notion of becoming "invisible," and mortality.
