I checked the ranking numbers for my novel, Saving Tiberius on Amazon this morning. Where it ranks in all 3 categories are excellent, especially in the Medical Thriller category, where it stands at #55.
In the other two categories, it's no slouch either. Of the tens of thousands of books listed on the website, Saving Tiberius, stands at #386 in Crime Action & Adventure and #658 in Mystery Action & Adventure.
Wow! Top 100 in one, top 500 in another and top 1,000 in an even broader category. I'm quite proud of this work.
It's also available in print and as an e-book from Chapters/Indigo and as an e-book through the Apple Books app.
