Help needed
Dear colleagues,
I struggle with two sentences- I īm not sure if they are right:
-The story made literary history as the first nonfiction best-seller FROM an African-American woman. 
Is the preposition FROM OK? 
-They are sure TO HAVE WORKED hard on the project. 
I expected the sentence: They must have worked hard on the project.
I would really appreciate your help.
Thank you.

From is correct. By would also be fine. 
They are sure to have worked hard/they must have worked hard.... both fine, similar meaning. You are surmising/assuming  that they worked hard.  
There is a difference in nuance: they are sure to have worked hard, it īs an assumption about them, but they second one, you are looking at the finished result; it īs excellent, so they must have worked hard at/on it.  So the first one is an assumption, but the second one is a deduction.
