Let's be crystal clear: Fourth Wing and Iron Flame are adult fantasy romance with explicit content, not YA despite the BookTok marketing making it look teen-friendly. Multiple parents who bought this for 10-11 year olds were horrified by what they found inside.
For adults who love fantasy romance with high stakes and don't mind graphic content? This series delivers. The dragon-rider world is imaginative, the protagonist's underdog story is compelling, and the 4.7 Amazon rating shows it entertains its intended audience well.
But if you're a parent whose middle schooler is begging for this because everyone's reading it—that 'everyone' better be college-aged. The torture scenes are graphic, the violence is brutal and constant, and the sex scenes are explicit enough that adult readers are skipping them. This isn't Percy Jackson with dragons; it's Game of Thrones at war college.
The WISE score reflects that this is well-executed adult entertainment that's completely inappropriate for the teens who are actually seeking it out. Know what you're getting (or what your kid is trying to get).
