Implementation of adding a book with a set of covers in Django

Conduct a code review. Assess the correctness of the implementation for creating a book and its associated covers, paying attention to potential issues with operation atomicity, input validation, and efficiency.

def create_book(data: dict):
    cover_list: list[dict] = data.pop('covers')
    new_book = Book.objects.create(**data)
    for cover_item in cover_list:
        BookCover.objects.create(**cover_item, book_id=new_book.id)
