      What if you discovered an infinitesimally thin material capable of conducting electricity, able to suspend millions of times its own weight, and yet porous enough to filter the murkiest water? And what if this incredible substance is created from the same element that fills the common pencil? That's graphene--a flat, two-dimensional, carbon-based molecule with a single sheet measuring only one atom thick. With a wide range of promising applications--from medical sensors to smart-phones and building material ten times stronger than steel--this revolutionary and highly adaptable substance is one of the most exciting developments in materials science in recent decades.--p.4 of cover

    • The Blacksmith would marry her. The Woodcutter would run away with her. The Werewolf would turn her into one of its own. Valerie's sister was beautiful, kind and sweet. Now she is dead. Henry, the handsome son of the blacksmith, tires to console Valerie, but her wild heart beats fast for another: the outcast woodcutter, Peter, who offers Valerie another life far from home. After her sister's violent death, Valerie's world begins to spiral out of control. For generations, the Wolf has been kept at bay with a monthly sacrifice. But now no one is safe. When an expert Wolf hunter arrives, the villagers learn that the creature lives among them - it could be anyone in town. It soon becomes clear that Valerie is the only one who can hear the voice of the creature. The Wolf says she must surrender herself before the blood moon wanes ... or everyone she loves will die.
