I need a summary of the book "90 days of different" not just the beginning, but the entire book. Spoil it for me, please. I just need to know what happens.

On the last day of high school, Sophie's boyfriend breaks up with her. It turns out he thinks she is too predictable, too responsible, too mature...too boring.

When Sophie turns to her best friend, Ella, for comfort and reassurance, Ella just confirms what her boyfriend has said. And that hurts even more.

Then Ella comes up with a plan to help Sophie find her wilder side before college. In the ninety days between the end of high school and the start of university, she is going to arrange for Sophie to do amazing, new, different and sometimes scary things. Sophie has to agree to everything no matter what. And she has to share her adventures through social media.
