The city of Fortuga, a secret haven for the Darkwalkers, is Vika’s best hope of finding out where her missing aunt is, for a cartographer lives here whose map can reveal the whereabouts of anyone in the Eight Worlds. However, the city teaches her an old lesson — not all wishes come true straight away, and things rarely turn out quite as one would like. On her way to her goal, Vika faces a whole series of trials and surprises: an encounter in the glow of a night-time rainbow, a dangerous pitchalka from which she must rescue a friend, and a difficult choice for the sake of her aunt, who has fallen into trouble. This magical story is the third instalment in the “Eight World” series.
