I Actually Did Write A Book Last Year!

Yes, you read that right. I did. Unfortunately, I did not realized I'd reached the end of it till it dawned on me that I'd segued right into the next book. How could I tell? Related, but separate cast of characters and problems. I've bene chewing on it for a couple of months.

Exactly where and how does one part of a story cut off, and the next one begin? That's something to ponger, cogitate, and masticate upon.
