Here's the blurb to Truly, Madly, Deeply, You :
Four days before Valentine’s Day, Liese Hansfeld is determined to shut the door to her house, as well as her heart, for her annual four days of mourning her one true love. Little does she know her best friend Freytag Meier is just as determined to keep her from her ritual. He’s ready to pick the lock to her apartment door and camp in her living room if that’s what it takes.
What Freytag isn’t prepared for is the surge of deep-rooted emotions he feels for Liese, but two things stand in his way: the grief and guilt she still clutches close to her heart, and a man who threatens to snatch Liese from under Frey’s watchful eye. Frey is determined to distract her into forgetting her pain. But is that enough to ease her grief, or help her see he can be more than her best friend?
