How is lyddie loyal in the book lyddie?

In the book Lyddie, the young girl Lyddie has two passions. These are: a deep-seated loyalty to her family and a desire for independence as is so common in a teenager. One example is, how she saves her family from an intruding bear as she stares it down while her family escapes to the loft. She then works tirelessly in a textile mill to pay off her family's debt on their farm.
