I'm... well, Lessing always leaves me... perplexed? Yes, but mostly, deeply uncomfortable.
Alice, our protagonist, is a pitiful, complex, deluded, spoiled child. She's highly intelligent, an expert manipulator, scary competent, yet victim of mistreatment by her... well, Jasper (that's one messed up relationship). We look through this ugly creature's eyes, and it's disgusting, and maddening, and absolutely compelling.
One itchy mental bomb.
