Married for the Boss's Baby

An unexpected baby… 
When successful surgeon Grant Smythe's baby half sister is orphaned, Grant is determined to be there for little Lily—unlike his own father. 
A convenient proposal… 
But a challenge for custody means Grant needs a wife, too! New nanny Sara Marcum is the ideal candidate… 
A wife forever? 
It might be temporary, but soon warmhearted Sara completes more than just Grant's family. Can he convince his bride-for-now to become his forever wife?
