there isn't a direct sequel, but the author did explore similar themes in their later works like 'The Wanderer’s Shadow' and 'Beneath the Silent Sky.' These aren’t continuations, but they carry that same haunting vibe.
Interestingly, some fans have theorized that 'The Wanderer’s Shadow' might be a spiritual successor because of how it mirrors certain motifs—abandonment, resilience, and hidden pasts. It’s not confirmed, though, and part of me likes that 'The Orphan' stands alone. Sometimes, leaving things unresolved makes the story linger in your mind longer.
