Bitter Sweet is the background story for The Chase, but both can stand on their own. I do recommend reading Bitter Sweet before reading The Chase though. For The Chase, I uploaded two chapters, chapter one is identical to the last chapter of Bitter Sweet (which means it is a major spoiler if you plan to read Bitter Sweet later), and chapter two actually starts to get into the plot of the story. I plan to wait to update any more chapters until I have quite a bit more content written, but I could be persuaded to update quicker ;D
Save The Chase to your library if you wish to be notified of future updates.
Enjoy reading!
