my worst best friend..reading challenge

this book is written in gracie's point of view...

this book is about 2 very different girls, gracie and savana.Gracie likes outdoors and iguanas while savanna likes shopping and beauty. they are best friends and they've planned all sorts of things they can do together, like rent an apartement together after college. one day, they decided to go shopping for Marilouise's birthday present. they agreed to meet at a coffee shop at the mall, at 10:30 am. gracie waited and waited for savanna for like, hours. she would be on her 2 or 3 cup of tea when cooper, her friend from school came by. he said that he was on his way to the meeting house and he asked her to come, instead of sitting there by herself waiting for savanna, she was always late. he said that she should leave a note by the cashier to savanna and say that she would be at the meeting house when savanna came by, because her cell seems to be turned off.. gracie finally agreed with cooper and followed him to the meeting house, everyone was happy to meet her and all the children loved her teaching too, she didnt feel like an outsider when she was there because they all love animals and care about the environment like her. gracie had such a great time there that she went to the cafe with some people. she only remembered about savanna when her dad asked her about savanna and thought that she was coming over after their shopping. gracie quickly called savanna to tell her sorry that she left cafe and savanna said that she never even arrived, and gracie said that if she never went with cooper, she would be at her 100th cup of tea by now. turns out, that savanna met a guy named morgan and she went on a date with him all day, she said that he was perfect.
the only problem is that he is a sophmore in college while she was a freshman in high school. she told him that she was 18 so he would be ok with it and not worry soo much about age difference. gracie thinks that she shouldnt lie, or even date him because she already has a boyfriend, archie and gracie also said that it is technically cheating.
savanna told her not to worry and it's about cheating when you're not married and it doesnt count because they only had one date.

what will happen next?
will savanna get caught?
what wll happen to her relationship with archie?
will gracie back up savanna like best friends do?
or will she do the right thing and tell archie the truth?
will they still be best friends?
