Persepolis is a strong option for learners who already feel comfortable with English and want a more demanding challenge. At an average of around 84 words per minute, the dialogue is generally manageable, though some exchanges require more attention. The language can be demanding, as characters often use less common expressions and more specific terms. There is enough plot detail to keep learners engaged without making the whole experience confusing. If your English is close to B2/C1, Persepolis can be useful for building vocabulary range.
