This time it's all mixed up...

Cynical, jaded, practical-minded attorney Jake Chastaine is still grieving his late wife two years after her death when he discovers that due to a mistake at a fertility center where she received treatment, a woman he's never met has had his baby. Jake is determined to play a role in his child's life. He's chagrined to discover, however, that the mother of his child is as appealing as she is impractical. A gorgeous redhead, Annie is a free spirit who raises llamas, reads tea leaves and believes her dead grandfather talks to her through highway billboards. Worst of all, she makes his body temperature soar in a most illogical manner.

When his law partner and former father-in-law threatens to ruin Annie in a misguided attempt to help him acquire custody of the child, Jake decides that the best way to handle the situation is to enter into a short-term marriage of convenience. They both get far more than they bargained for, and learn a life-changing lesson about the power of love.
