"Hotels of Pyongyang," not Summit Springs.

 

The book is Hotels of Pyongyang, by James Scullin and Nicole Reed. I may need to get this one for Christmas.

   

The curious design features of North Korean hotels at The Economist

A book of photography offers an offbeat look at a little-seen city

...the book’s main interest is in the unique design features of the hotels. Even those few Westerners who have ventured to North Korea are unlikely to recognise most of them (the vast majority of visitors to the country are Chinese). Because of the pandemic, North Korea has been off-limits to overseas tourists since the end of January. So, for the moment, those tempted to go—and the many more who never will—can get no closer to a Pyongyang hotel than Ms Reed’s engrossing pictures.
