What Authors Say About Mariah Sinclair Book Covers:

“

My contemporary cozy series had dismal numbers and never sold well. In fact, I'd given up writing the series even though I loved it. I couldn't justify the time. After Mariah Sinclair designed new custom covers for the series, the sales numbers tripled. That's right...TRIPLED. In fact, I recently put out a new book in the series and it's doing well. Mariah is incredibly professional and easy to work with and she comes up with the most beautiful covers.

Mariah Sinclair knows how to make book covers pop. Clever, well put-together, with just that special touch. Her pre-mades tickle the imagination by themselves.

I have a premade trilogy from Mariah. I can’t count how many people have said, “Those covers are AMAZING.” It’s almost gotten old—wait, no it hasn’t; I can't get enough of the compliments! They are incredibly eye catching and so great for the genre. Great covers sell books. I even got a BookBub Featured Deal on the first book in the series, and I think the cover played a huge role in that.

Mariah's unique cozy mystery covers and penchant for titling are so incredible that I bought a set and convinced myself to write a cozy series. No one person should have such power! I sincerely believe that her creative cozy mystery covers have directly correlated in an uptick in the genre's popularity. She's that good. Recommend highly, 10 out of 10.
