Sam and Lucy seem like the perfect couple. Successful, happy and in love. But life isn't that simple. Lucy thinks thinks Sam is a sad, cold sensitivity-exclusion zone who would rather read a newspaper than have an emotion. Sam thinks Lucy is blaming him because she can't walk past Mothercare without getting all teary. The problem is that they might be infertile. And in more ways than one.

Lucy wants a baby. Sam wants to write a hit movie. And given that the average IVF cycle has about a one in five chance of going into full production, Lucy's chances of getting what she wants are considerably better than Sam's.

What Sam and Lucy are about to go through is absolutely inconceivable. The question is, can their love survive? Or are the odds stacked against them once again?
