Bina Birnbaum is the strongest witch of her generation - which unfortunately hardly anyone knows. All the more enthusiastically, Bina throws herself into her newest mission: lifting the curse placed on the neighboring werewolves, the Martins. At her side is the wood elf Cianán, who is only just discovering the world outside his forest.
However, their mission turns out to be not as easy as they thought, and also awakens ghosts of the past that soon put Bina and her friends in quite a predicament ...

Bina and the Darn Curiosity is the fifth book of the series "Of Elves and Wolves" and the first of the Bina arc.
