I've troubles understanding why the tenses for the following sentence should be in the past:
The last book I have read is Animal Farm, and it's really good.
I've been corrected (not from a native), stating that, instead of using the present-simple and the present-perfect, I should use the past-simple:
The last book I read was Animal Farm, and it was really good.
I understand that the past-simple for read may be preferred since it's a finished action in the past. But, that book still is the last book I read, and the book still is good.
If that book was a pizza, I may understand that you won't be able to eat it again, so it was good, but a book still is: unless I'm not sure anymore, or I don't have an opinion anymore.
