Harry Potter and The Deathly Hallows - This Kid Should Be Alive!...Just in Prison.
In Chamber of Secrets, it is revealed that Colin Creevey is a muggle-born. That's why I found it odd that he DIED in Deathly Hallows, because earlier it is explained that, under Voldemort, muggle-borns can't go to Hogwarts. This means that Colin should not have been there for the final battle.
