Miles and years are always retractable. Whilst some bonds are unbreakable, others that lie in tatters are there to be renewed. And sometimes it takes a death to help a family to live again. After receiving the devastating news that their brother, Matty, has passed away, long-estranged feuding twin sisters, Imogen and Isobel Parkhouse, are forced to reunite. In his will, Matty offers them a great fortune, but they must go on a treasure hunt - together - if they wish to receive it. Although they set out with great reluctance, they soon find that 'the great horcrux treasure hunt' has far more reward in store than they ever imagined.
