Rei and Kira are from different worlds.  Rei is a complete player- he hustles on the basketball court for money, races his motorcycle, and has a reputation with girls.  Kira is a quiet art student- shy to the point of almost being mute, she is disliked by her classmates and spends all her time drawing and painting.  When Rei and Kira unexpectedly cross paths, Rei is taken by Kira’s talent.  When she asks him to model for her paintings, he agrees and as they begin to spend time together their connection deepens.

Mars is a graphic novel romance.  Rei and Kira love each other, but are both damaged people whose lives get in the way of their happiness. It is a fun, quick read, that is part of a series.
