What age is The Goldfinch appropriate for?

Could you elaborate on the suitable age range for reading "The Goldfinch"? Given its themes and complexity, I'm curious if it's appropriate for younger readers or if it's more suited for an older audience. The book deals with some mature topics, so I'm wondering if there's a general consensus among readers and critics on the appropriate age bracket for engaging with this particular novel. I'd appreciate your insights on this matter.
