This book was a nice, quick summer read. Although the content was at times pretty heartwrenching, as any story about losing a family member to dementia would be, it didn't get to me on a super deep level. I didn't find myself thinking about the characters when I put the book down. In a way, it almost reminded me of the young adult lit that I consumed like candy back in middle school and high school, that use witty humor to cover hard-hitting family issues. I usually enjoyed them in the moment, but they never packed a huge punch, and the same is true for Goodbye, Vitamin.
