The protagonist of this mild satire - is a human brain floating in an aquarium - The bodiless Ypsilon, expected to be an unemotional intellect, feels lonely. Beause he is lovesick over a pretty lab assistant, Ypsilon chooses not to respond to elaborate educational regiments - With the aid of a chimpanzee and a detached human hand, he makes detailed plans for an impractical escape - Amusing and phantasmagoric." - Publishers Weekly. "Thanks to [Lesser], Ypsilon has become as convincing and many-facetted to the English-speaking audience as he is to his Swedish readers, and the ethical and wider human problems posed by his situation have become just as urgent." - Swedish Book Review.
