Puzzled at Christmas

Living in Chicago, Hannah Griffin has just about had enough of the brutal winters. Unfortunately, that's the price she has to pay for her dream advertising job. But ever since her boyfriend broke up with her and moved to San Diego six months ago, the job hasn't seemed quite so fulfilling. Now, a little over a week until Christmas, Hannah finds a brightly colored envelope on the floor just inside her front door one evening.
Cautiously opening the envelope, Hannah is told by a secret admirer that for the next nine days, she will receive an envelope each day containing a puzzle piece. By the end of the ninth day, the admirer's identity will be revealed to her. With her best friend, Cassie by her side, the next nine days become a whirlwind of gifts, speculation, and finally revelation. Will the ninth envelope reveal Hannah's true love, or will disappointment find her once again?
