Answer: No, it is not a run-on sentence</h3>
This is one full thought that doesn't run on for too long. The "overcome with joy" portion is the dependent clause that needs the other part "Mrs. Monroe told her husband the exciting news about her promotion" which is the independent clause. The independent clause could be its own sentence without the dependent clause, but not the other way around.
Answer:
The Order is a group of wizards, led by Hogwarts headmaster Albus Dumbledore, dedicated to fighting evil Lord Voldemort and his followers. ... Harry used magic to fight off the dementors, and since underage wizards are not permitted to use their wands outside of school, he must face a disciplinary hearing at the Ministry.
That is the summary of the, book you should pick what you like and turn it into one sentence.
1st person pronouns= I, me, we
2nd person pronouns= you
3rd person pronouns= he, she, they, them, him, her
