The third and fourth novels of the tetralogy of Rhombus Varden. The world of the rhombus Varden is four planets from which it is impossible to escape. Special microorganisms infect everyone who has stepped on the surface of one of the planets, not allowing them to move away from it, but in return endowing people with paranormal abilities. The fact that it is impossible to escape from these planets made them an ideal prison for the best criminals (those who are sorry to kill, but scary to plant).
