This is one of the Lone Star Books I’m excited about. This text is told in a unique way: text messages, letters, sticky notes, emails, and more. So it is like Illuminae in that regard. This one is not set in space though.
The Texas Library Association puts out a Lone Star Reading list every year. They just released their 2020 list last week. I try to read as many of them as I can each year and I'm never disappointed! The books are selected by librarians across the state. The books are well written and highly engaging for teens and adults.
