There are two things Ben Schumacher can happily live without: sex and Christmas.

All Ben wants for Christmas is to be left alone (and maybe to snuggle by a fireplace with a cute guy). He is sick of the holiday season with its real Christmas trees, whimsical traditions, and overall cheer. 

The Heart 
Troubled by Ben's lack of Christmas cheer, a mysterious (and frankly creepy) old man gifts him with a glass heart that glows when the beholder is full of Christmas spirit. Its light extinguishes as it falls into Ben's hand. He's soon offered a challenge to make the heart glow before Christmas. A challenge he ignores. He has better things to do than save Christmas. Like snuggling with a cute prince.

The Prince
As the Christmas season begins, he's dragged to the quaint county of Mistelvia to visit his cousin, Julianna, who just happened to marry to a prince. On his first night at the palace, he run into Nikolas, a scruffy book nerd and Julianna's brother-in-law.  Last Christmas, the two bonded at Julianna's wedding and became friends. Now both single, it seems like Ben will get his wish to snuggle with a cute guy; however, merry misfortunes throw a wrench into his plans as Christmas is attacked by a mysterious spirit known as Grumpus.  And the only way to stop this malevolent force of Christmas mayhem is for Ben spread a little holiday cheer.

Because Grumpus only goes when the Christmas Heart glows.
