This is John Green's memoir hidden inside a cute package: reviewing things in the world that don't usually get reviews (Teddy Bears, Air Conditioning, Sunsets, Plague, and on). In some ways, it's the memoir of someone who may think a story about them isn't interesting enough.
Whatever it is, it's beautiful. I've been aware of John Green's long YouTube presence and impact to internet culture, but had never read his novels. So, this may be obvious to anyone more exposed to his work: John is a beautiful, gifted writer. There are moments of joy, intense interest, and deep sorrow. One of the most enjoyable reads of the year.
