Critique Your Young Adult Novel's First Page for an Authentic Teen Voice

You are fairly sure your protagonist sounds seventeen, but you wrote the page as someone considerably older than seventeen, and that gap shows more than you think. This checks voice, vocabulary and stakes against what actually lands for a teenage reader, and flags the exact lines where the register slips.

**Critique the opening page for authentic YA voice:**
1. Check whether the narrator sounds like a real teenager, not an adult writing what they imagine teenagers sound like
2. Check that vocabulary and reference points land for the target age without being try-hard or dated
3. Assess whether the stakes in the opening page would matter to a teenage reader specifically
4. Note anywhere the voice slips into an older or younger register mid-page
