If it is a derivative, yes. As a CC-BY-SA licensor, I expect the
derivative works to be available to recipients with similar rights as
CC-BY-SA gave you. It's not a matter of size. Though, there's too little
information to know if your work is indeed a derivative work (in CC
parlance, an adaptation), or a collection, or other cases such as fair
use of the material for specific purposes.
For example, works known as sequels or fan fiction don't necessarily
contain even 1% of verbatim copied material, but they are based on the
original work, use its characters, are set in its world, refer to its
events. They are remixes, many consider them derivative works.
If the original work is under copyright restrictions (the default
copyright law), then these works are infringing, and their authors at
best tolerated. If the original work is under CC-BY-SA, then works
building on it are free to develop. They just should keep offering the
same rights to their readers as the original gave them: CC-BY-SA or similar.
IMHO, your best course of action is to ask the author of the work. Note
that ShareAlike licenses allow commercial use.
