ÒThat Has Children of Demon KillersÓ is the first book in the series. It about five teenagers who locked them with other customers in a mall on top of the mountain because they heard a loud explosion.
ÒI Know A LandÉÓ does not have any adult materials, no strong language, but it has a respectable amount of action and violence. It is a great book for the middle school kids to adult age (10-99+). It is easy to read; it will be great for English Second Language students.
