In Goodbye, Vitamin, we follow Ruth, a girl who quits her job and moves from SF back home to take care of her father with dementia. Through Ruth's eccentric narration, she reflects on her romantic relationships, friendships, and, most importantly, Ruth's connection with her dad. While her father is slowly losing his memories and mixing up events, Ruth and her family must come back together to forge a new relationship with this sometimes brilliant and sometimes childlike man.

I adore Khong's luminous and poignant writing in Goodbye, Vitamin. Even though the subjects of family drama, Alzheimer's, and infidelity are serious, Khong employs a unique and humorous voice to take the readers through these heavy topics. As many have pointed out, the writing style is very similar to Weike Wang's Chemistry, and readers who've enjoyed Wang's books will likely find parallels in Goodbye, Vitamin.

I personally like this book a hair more just because any topic on taking care of ailing parents always hits my soft spot. As someone who lives halfway across the world from my parents and hasn't seen them in person since the pandemic, it's extremely tough to learn when they are sick since I can't just visit and take care of them on short notice. Goodbye, Vitamin explores the intersections of adult children coming to terms with their parents' past and hoping to now take up the mantle to bring a brighter future for them with the limited amount of time we all have.
