Country vet Primrose Cartwright knows more about heartache than most but in the close-knit community of Ballimore, she's found a place to call home. Prim has her work and the love of her sisters, and she doesn't need anything else - certainly not Blake Sinclair.

The new vet in town, Scotsman Blake has a love-them-and-leave-them reputation. He is curiously protective of Prim, but his privileged upbringing and jet-set life are nothing like her own. Prim has tried - and failed - at the dating game. Even if there's a burning attraction between them, the last man she could ever trust is Blake.

Blake finds Prim fiercely independent, vulnerable, and unlike any other woman he has ever known. But Prim won't tell him her secrets unless he tells her his own, and Blake's pain is buried deep.

Will Prim's determination to unravel the mystery that threatens her career bring Prim and Blake together or tear them apart? As the storm clouds gather, can Prim and Blake confront their painful pasts and create a future together? Will they find the sunshine through the rain?
