What does it mean?

[tahtaar]

Dear teachers,

I read an article about the lost land "Atlantis". At the introduction they say " The discovery of Atlantis and the case for Cyprus is presented in eight chapters, each with a uniquely different focus.

I would like to know what the phrase in bold means.

Thank you in advance

I'd say that the phrase "uniquely different" means the same as the simple word "different", with "uniquely" just giving emphasis to the fact that each one will be distinct from the others.

The focus of a chapter would be the point of view of the chapter, the particular things it will discuss. I can only guess, but in this case, one chapter might be concerned with myths, another with documented history, another with geography, another with geology, maybe another with language, another with DNA studies of the residents, etc. Each would have its particular focus, but all would be about Atlantis and Cyprus.
