The Glass Children. Enjoy New Translations, #4

When Tristan Kolev, a failed observer with a talent for seeing too much, is recruited by a mysterious Chinese consortium to study the psychology of mass pleasure, he believes he has been hired to write reports. Instead, he discovers an invisible economy built on the extraction of human joy itself. Behind the all-inclusive smiles, karaoke nights, and insurance policies against alien abduction, Sunny Resort is harvesting something far more valuable than money: wicked joy.
The most ecstatic tourists vanish, their memories rewritten, their excess happiness redistributed to distant corporate elites-and to something even more unsettling.
