Silver Bells by Anne Shaw

Alice had to act, and she had to act fast: a girl’s life depended on it.

A series of coincidental events leave Alice with more questions than answers. Could the sick little girl in need of a bone marrow transplant be the daughter she gave up for adoption ten years before? To become close to the girl without revealing her identity, Alice develops a plan to cast the girl’s uncle, a chocolatier, as a contestant on a live Christmas Eve show.
A television cooking competition was never in Niko’s plans, but when his sick niece expresses her wish for him to compete on the show, he reluctantly agrees. His past as an MMA fighter taught him to guard himself from punches being thrown his direction, but he wasn’t prepared for the fallout of letting his emotional guard down for Alice.

When sparks fly between Alice and Niko in and out of the kitchen, will the secrets Alice keeps shatter the budding relationship?
