Sarah

Sarah is a character in Deeper.

She is Jake's younger sister and closest friend. Despite the problems that the family has faced over the years Jake and Sarah have grown up to be very caring toward each other and the two are almost inseparable.

That isn't to say that their existence together is peaceful. Like all siblings they have been known to squabble and banter. Jake often plays practical jokes on Sarah and she often dances around in an attempt to get a rise out of him. These little spats usually end fairly quickly and Lucy rarely has to intervene.

It is unclear as to whether or not Sarah is as naive or innocent as Jake as she is more of an extrovert than he is, making if more likely that she has at least a greater knowledge on sexual matters.

At the beginning of the story Sarah is seriously ill. She is so weak that speaking and moving are extremely difficult for her.

Just as Jake's age is never mentioned during the story, Sarah is also "Ageless" although it is stated several times during the plot that they are both young-adults.
