What earns this book 4 stars is the additional information that the author includes at the end of the book, after the story ends.
Lauren Tarshi has made a career out of writing these teen books in her "I Survived" series.
These stories include: I Survived" "Pearl Harbor", 9/11, D-Day, The Great Chicago Fire, and 19 other events.
This writer was new to me, as was her style. I suppose if I had to specifically label it, I would call it "Teen- historical fiction". She places the fictional (teen) protagonist in a very realistic setting and tells the tale of the disaster around them.
What I found fault in this book was that in my opinion, she spent too much time in "setting the table", dwelling on the back story of our hero Jackson's life in the Alaskan bush. He shows up in Valdez, towards the end of the book, and bang, the earthquake hits a few days later!
The author redeems herself by following the story with her field notes from her research trip to Valdez as she was researching her book. Then she explains , in the clearest way that I have seen, the science of Seismology and of plate tectonics ever defined.
The book is written in a way to encourage strong values, independence and sound reasoning among its teen readers.
