How we cite our quotes:
[Bella to Edward:] I was grudgingly honest. "Not in Phoenix…" (12.76)
Bella had no love life prior to meeting Edward, so both she and Edward are in the same position – this is their first experience with love.

Bella feels no fear. Instead, she's completely attracted to Edward.
