The narrator temporarily works in a small pet shop. She lives with Sylvester, a swarm of women who has a lot to do with being denied in front of his admirers. One evening Matilda knocks on their door to find shelter together with the biggest dog in the world. Matilda has a problem. She thinks she's losing her mind. The trio, welded together by necessity and affection, sets out to defeat an invisible monster. Mariana Leky manages to make this fight against dizzying windmills sound like a film comedy: a novel about panic and other plagues that is as amusing as it is moving. Fear can only be overcome by those who challenge it. Mariana Leky's first novel tells of friendship and fear: a first-aid kit for the pitfalls of everyday life. Their timid heroes stick together because they are.
