Outcast by Adrienne Kress
I absolutely adored this cover the first time I saw it,, and I still do. The dark shades of the blue in the night sky and the moon with the couples' silhouette is fantastic and fits the cover and the title perfectly. Also love the creepy and mysterious feel of it. The title and the author have been given their good space, but the little quote at the top is not really clear, which is a small problem somehow. Don't you think?
