Check out this post for Belgian reviewer to compare different covers of the same book.
I have recently read the Child by Fiona Barton. Based on that, I would read another with her name on. When I read the child, I saw a poster in the train station and next day the book was in a charity shop for £1, so I bought it. Do not think the cover designs are great they are very bland.
Out of two for Widow would choose the White.
I have read Big little lies and love Liane Moriety books. Can not remember, which cover I had.
The Tattooist of Austwich sounds interesting based upon the title.
