Izzy McBride had never in a million years expected to inherit an actual castle from her great uncle Bill but here she was, in the run up to Christmas, Monarch of her own Glen – a very rundown glen in need of a lot of TLC if her dream of turning it into a boutique bed and breakfast was to come true.

But when Izzy’s eccentric mother rents a room to enigmatic thriller author Ross Adair and the Scottish snow starts to settle like the frosting on a Christmas cake, it’s a race to get the castle ready before they’re all snowed in for the holidays.
