This is the link to POTC3. I will post the link for 4.
Just to clarify, it's on fanfiction.net. Search "willofthewisp" for pen names and you'll see my name with 3 in parentheses. Click on that and choose one of the three stories. A Phantom of the Opera fanfic, POTC3, or POTC4. Only the POTO one I did alone, so leaving a review will really be reviewing for the whole forum since so many people participated in the stories.
Chapter 4 is up for POTC4. This is where I think the story really kicks off. The thing is, it still has no reviews! Where is everybody? Please, it really is good and I won't mess with it for a little while to get people begging it to be continued, so take advantage of the time, get caught up with the reading, and then read both fanfictions. We all worked hard on them.
