I need a recommendation please

[Sajjad]

I am going to Cuba for a week and want to take a book with me. I am interested in books that deal with the following:

1. A mysterious scientific or archaeological discovery that baffles, kills, etc.
2. Global health crisis due to some new strain of virus, bacteria, etc.
3. Animal encounter or animals going crazy (e.g., Zoo)
4. An expedition facing a unknown creature

I would appreciate your assistance.

Thanks
Sajjad
