A lot of reading

Jenny follow her mother outside before she comes back. But she's shocked on how much detail there is in this book, how her mother was dressed, what she was thinking at the time, how handsome was her father. It's insane, how her uncle knew that much ?

She looked at her mom as she was closing the front door.

"Mom, did uncle Gabriel was a writer ?" She asks.

"Gabriel ? No, not that I know." Her mom answers.

"We're going first, you'll join us at the garage sales with your part of the stuffs ?" Her cousin Tracy yells from her car.

She's around the same age as Jenny, a little bit prettier and a lot meaner when she doesn't get what she wants. She's her other uncle's daughter, and a little bit spoiled.

Still confused about the book Jenny look back at it only to discover that the story have changed. It's not about her mom now, it's about Tracy. It talks about how she bullied a girl in high school, it's just one prank during a specific day, four years ago according to the dates above the page. Again, it's described in a lot of detail.

The book, it shows in detail the life of someone... So... Is it possible ?

Jenny looks two years ago, when her boyfriend disappeared for half an hour and came back acting weird. Tracy was there... and the book tells her what happened. It confirms her doubts, they slept together ! Those little shits... Wait... Jenny looked further... it isn't just a one time thing, they did it multiple times theses last two years !

"Stop, reading that book and get in the car for Christ sake !" Yell at her, her mom.
