A solid three stars.
It was a quick read, I flew through the book in days, however, I did expect something a bit more 'thrilling' or with a bit more depth.

I liked that the man was the one who was obsessed with having a baby, as it's usually women portrayed in this role. I didn't mind that the science was flimsy because I don't wanna be reading a science book!! 

I expected more from the 'plot twist' & ending which was a bit disappointing.

Overall, I didn't love the book but I didn't hate it either.
