Your storybook timer will end Monday at Midnight PDT. So you will have tomorrow to complete day ten.
I'm one day behind you and my timer ends at 2am CDT (my time zone) early Wednesday morning, so I need to have everything completed before I go to bed Tuesday night. I am currently on on chapter 8. I have everything ready to upgrade to level 8 but I still have the chapter open so I can collect from my fountains.
