Four curvy heroines. Four deployed soldiers. Four love stories—and they all begin with just one letter.

It started with One Letter. Kellie sent one letter into the Middle East and Sargent Daniel Rodriguez was the one who answered. Despite an ocean between them, love blossomed. But can you truly love someone you've never met?

It began with One E-Mail. Madelyn sent out one e-mail to the most feminine name on a list of deployed soldiers–SFC Taylor Russell replied. They exchanged e-mails for months, until somewhere along the way they stopped exchanging words and began exchanging pieces of themselves. Their love blossomed quickly, but will it prove strong enough to survive the test of family?

It happened One Christmas. Jane wrote a letter and Sgt Brad Wilcox replied. Despite their age difference, they connected with their words. But when they finally came together, their differences became glaring. They'd already conquered distance, but will they be able to overcome the years between them–or will their time together be limited to one Christmas?

It was sparked by One Note. Lauren sent a note of encouragement to her newest assigned soldier–Private Mason Carter was that soldier. Despite their attempts to remain guarded with one another, the walls fall fast, and then in the blink of an eye the unthinkable happens. No stranger to loss, Lauren is faced with a choice–run to him or run from him. Either way, their hearts will never be the same.
