Ugh if this was gonna be the sole chapter for a while I wished it ended with a clearer ending for a chapter. It kinda just cut off....but I am interested and I hope the author will create more in the future.
I believe the word you are looking for is cliffhanger. And ending chapters with cliffhanger is the norm lol, gotta makes people want to read more for them to come back.
Also, I hope the author is just taking some time to prepare for this series instead of dropping it.
Or maybe this is just a teaser for a novel, and not a series at all?
