A Christmas treasure hunt is the beginning of a unforgettable journey of love and second chances...

For as long as Cassie can remember, it had been the three of them: Cassie, her big brother Tom, and Tom's annoying best friend Sam.

Now, Tom is sorted, Sam is flying high, and Cassie thinks she's figured it all out. Then, unexpectedly, three become two.

For Cassie starting again seems unimaginable. Until she finds an envelope with her name on it, with a letter asking her to follow a trail to one last gift.

And, suddenly, what seemed like an ending promises Cassie something surprising, remarkable and new... if she is brave enough to follow her heart...
