I'm still looking at the covers.

Isis Sousa has mocked up a bolder cover with bigger text and more emphasis on the author:-

I'm still not sure whether to emphasize the series name as the brand or the author name. I do think the book title should be a little bolder.

What do you think? Which cover looks best?
