Hi Tim! Good for you! I checked out your books, and the Kilimanjaro title caught my eye.

I mainly write romance novels, so this travel series doesn't get my full attention. And the sales reflect that. :-)

Some in the series have been easier to market than others. For instance, Korea did the best at launch (and reviews) no doubt due to the trending interest in all things Korean.

My newest, Antarctica, has gotten stronger sales than my other launches, without any marketing other than Medium and Facebook. As I continue to build my travel series, my hope is that some read-through will spill over. Hope that helps!
