Didn't read the first.
I haven't read the first book (neither have I seen the movie) so I wouldn't really jump in to the sequel immediately. And it's a little "in the uncanny valley" right off the bat. Why would a plastic surgeon ask a widow if she loved her husband? And she doesn't think this is strange?
Regardless, this doesn't seem like the book for me.
