Two Makeshift Christmases

Drew Roberts is an orphan. It's lucky for him that his stepmother still wants him around. It's lucky for her that he's there to look after his half-sister Monica. With Drew's father's recent death having shaken the family, it seems unlikely that Santa will be stopping at their apartment this year. However, Drew knows that this will break his little sister's heart, and is determined to make this year the best Christmas, ever.
With his memories intertwining with his idea, and the influence of his mysterious older sister Riley helping him at every turn, can he pull off his plan before the big day?
