Hourglass

Hourglass by Claudia Gray, 2010 Harper Collins

     Bianca has decided to escape Evernight with Lucas, but their life with the Black Cross (the vampire hunting community Lucas comes from) becomes more and more difficult. Bianca requires blood to stay alive, and her substitution of pigeon blood for human is not working. Lucas insists on feeding her his own blood even though Bianca is adamant about not wanting to suck the life force from her love.
     The couple plan their escape from Black Cross, but Lucas' stepfather keeps a tighter and tighter watch over the group. As Bianca becomes weaker and weaker the two fear that her secret will be found out. When they finally make a break for it, the Black Cross has come across Balthazar (a vampire from the academy) and the two run away when Lucas' parents' backs are turned during the battle. But Bianca hasn't had enough blood and is dying. Balthazar escapes and catches up with them, only to find he is about to lose his friend. The former enemies begin to bond as the situation becomes more and more dire.
     While Lucas and Bianca's relationship is still following the lines of Romeo and Juliet they have moved from the puppy-dog love to a kind of romance that allows for their strengths and weaknesses to be a part of the relationship. They develop as characters separate from one another and deal with the challenges they are presented with. The story is written for a younger high school audience, but has elements readers of all ages can identify with.
