I need help. 1. Where did Willow go to hide after she ran away from the hospital? 2. How did Mai bully Dell Duke at the burger and pie diner?

3. When sending documentation to the principal, why didn't Dell hand over

Willow's test results?

From the book "Counting by 7's"

1) Willow is taken to the hospital where she passes out and hits her head, After getting stitches, she runs away from there and goes to the Library and hid behind a large chair

2) Mai bullies Dell Duke at the burger and pie diner as she ordered alot of food and then made Dell to pay for it.

3) Dell Duke gave Willow a test like the one she was accused of cheating in and she aced it. If Dell had handed over the test scores, principal would have realized that Willow didn't cheat in the exam after all, and Dell Duke's incompetence would have been discovered.

may i know the title of the book?
