It's been seven years since two students opened fire on their high school, killing 13 before taking their own lives.
The residents of Littleton, Colorado, say they are are continuing to heal after the massacre at Columbine High School.
Classmates Eric Harris and Dylan Klebold terrorized the school for hours before killing themselves.
Former student Marjorie Lindholm survived the attack and now at 24 says she has only recently begun to heal.
With the help of her mother, Lindholm has written a book titled, "A Columbine Survivor's Story."
In it she details how life has been very trying for many families who lost loved ones or had their lives forever changed.
The attack on Columbine was the deadliest school shooting in the nation's history.
