Also there are endless series that are already significantly in progress.
Seek those out instead. Much more satisfying.
My advice to any avid reader is to avoid any series that only has book 1 out, unless you’re 100% prepared for the risk of abandonment.
Melanie Rawn’s Exiles “trilogy” taught me that in the mid-90s.
Only ever start a series that’s at least 3 books in - unless it’s a duology.
These days, I favour series that have a good 5-10 books released.
Also, be very wary of authors who are too interested in stretching out answers to mysteries. Cliffhangers are only good if eventually resolved.
if someone wants to sift focus for a few years before resolving dangling plot lines, to hell with them.
