One irrepressible city girl plus a by-the-numbers accountant = a tricky equation...

For city vet Isabella Passmore, the opportunity to pet-sit in the country knocks at the perfect time. Bring on that fresh air! But after three days of holiday bliss, Izzy is bored silly. If the air gets any cleaner, she'll start slinging mud. Then she gets offered work in the second-hand shop. Saved!

Maybe.

It's been years since Elliot Field's parents rolled out the red carpet, but Elliot only needs one day to learn that this welcome mat comes with strings. His parents' new business is sinking, and they expect him to fix their financial problems.

To prepare for the week from hell, he'll need a mug that's not steeped in bad memories, but nothing could prepare him for the employee he encounters at the second-hand shop.

For Izzy, pursuing Elliot is a most welcome diversion from walking another lap of town with the dog. For Elliot, their random encounters add up to the sum of much bigger things.

He's always been a numbers man and he's kept his heart locked away, but in irrepressible Izzy, is Elliot's number finally up?
