One topic that tends to intimidate students learning German is the use of these four words: Wessen, dessen, deren, and denen. They are indeed tricky, but they make it possible to construct elegant sentences and are therefore very good to get acquainted with!
Wessen, dessen, and deren can all be translated as "whose." However, unlike "whose" they are each only correct in certain situations. Wessen is related to wer, wen, and wem, i.e. it is asking "who?," but it is possessive. It is used when the "who" of the sentence is not known and could therefore be any gender:
Sach ma [Sag mal], wessen Freundin bist du eigentlich?
Tell me, whose friend are you actually?

Dessen is used when the person or noun in question has already been named or referred to, and is masculine or neuter:
Acht Minuten später schickt der Paulianer geschickt Julian Schieber,
Eight minutes later the "Paulianer" skillfully sends Julian Schieber
dessen Schuss aber knapp vorbeigeht.
whose shot, however, just misses.

Deren is used when the person or noun in question has already been named or referred to, and is feminine or plural:
Seine königliche Hoheit, der Prinz,
His Royal Highness the Prince
wird die Frau heiraten, deren Fuß in diesen Glasschuh passt.“
will marry the woman whose foot fits in this glass slipper."

Wessen, dessen, and deren are all genitive relative pronouns. The relative pronoun denen, however, is used for relative clauses involving a plural noun in the dative case, with prepositions such as mit, auf, nach, or bei.
Es macht einfach Spaß, mit denen Zeit zu verbringen.
It is simply fun to spend time with them.
