Vicente (The Santinis #4) by Melissa Schroeder

Marine officer Vince Santini has loved one girl since high school.  His problem was that she married his best friend.  Now she is a widow and afraid to love again.  Can he convince her to give him a chance this time around?

This was the sweetest of the four Santini brothers stories.  I actually teared up at one point.  Vince like his brothers is strong and sexy.  Despite his strength his relationship with Julianna leaves him endearingly vulnerable.
