I think the last part summed up the book really well, bringing us back to where it all started, at Kitum cave. I thought it was really brave of the author to go explore the cave, knowing it might be covered in lethal viruses. However the only things he found out were that it was not a dry cave like he had expected and it was carved by elephants. The author also went  to the monkey house and saw that a spider was in there, which means it could possibly bring Ebola back. That freaked me out a little along with the last line of the book, that says, “It will be back.” When the book ended, i still had a lot of unanswered questions. Whaat happened to Nancy and Jerry Jaax? Where did the virus come from? Will the virus change if it comes back? This book was pretty good overall, even though it got boring at times.
