Berg Judit - Rumini Tükör-szigeten (2019)

Enough of the adventures!
When the crew of the Wind Queen rest in the Pearl Lagoon, sunbathe and swim in peaceful ice cream, they surely feel that now there will finally be peace around them for a while.
But of course it wouldn't be a real Rumini book if their calculations weren't crossed by some seemingly harmless, but all the more dangerous mercury, whose poison will not only make Rozi Sajtos a mind reader, but if they don't do something urgently, her whole body will turn to silver. ..
The antidote is said to be found on a certain Mirror Island. However, there are two identical islands in the place marked on the map! One is a mirror image of the other, and both are very dangerous! But which one is the real one, and where is the medicine hiding?
All secrets are revealed in the ninth part of Rumini, even what is hidden in the depths of the mirror!
