Investigating the Attacks on the World Trade Center [PDF ebook] 

The world watched in horror on September 11, 2001, when two passenger planes were flown into the World Trade Center buildings, killing nearly three thousand people. Soon after, the United States entered a war that would last many years. This book explores the events leading up to this horrific attack and the terrorist group responsible, as well as the attack itself and its long-lasting ramifications. Students will be guided in their reading with a timeline, a glossary, and a further information section to encourage a deeper understanding of the topic.
