Sure!

R. Paxton 's Anatomy of Fascism includes sections on Italian Fascism. It is also relatively recent, so that its bibliography is a good reference for further sources.

S. Payne discusses Italian Fascism in the general context.

More recently, R. Bosworth, whose work I am not entirely familir with, focuses more directly on Italian Fascism.

Among non Italians, remember G. Mosse and also Mack-Smith's work on Mussolini (which is a bit dated by now).

You may want to check C. Seton-Weston's Italy from liberalism to Fascism.

And I am sure I'm leaving out many others.

You could also look up Hannah Arendt. She wrote on Totalitarianism as a topic and discussed different forms and origins of them at various places. The Origins of Totalitarianism is the name of her book.

It wouldn't fully be about Fascist Italy, but she does talk about it.

Are you interested in material by Italians in English translation? Can't tell from your question. If so, strong recommendation for Alessandro Portelli's The Order Has Been Carried Out. Portelli is technically a literary scholar, but this is one of my favorite works of history across all fields.
