Birthdays have never been something Nora Terre marks on her calendar. After her memorable sixth birthday, when she first discovered she can World Walk between Realms, they’ve all been downhill since. Take her twelfth birthday for example: her mother died in a car crash, and her father, overcome by his grief, destroyed Nora’s last connection to her family legacy of World Walking.  
 
Stranded in the Twelfth Realm, Nora is forced to adapt to a normal life, if one could count her father’s continued absence normal. By happenstance, as another dreaded birthday approaches, she finds a way back to her favorite of the Forty Two Realms. But her tiny moment of happiness is shattered when her father’s own demons start searching for her, and a betrayal from a friend leads her back to another Realm she thought she had long ago left behind.

 " I have a confession to make: I am a vampire. Or, to be completely honest, I am half-vampire and there lies my problem. You see, to be a vampire or to be a werewolf or to be any other supernatural creature is easy. There are schools, jobs, communities, but to be a half-blood, to be a hybrid, leaves someone out in the cold. There are rules to follow as a pureblood, regulations to help them blend with humans, but if a person’s blood is tainted, we are sent away, to the furthest outskirts our families can find, in order to become whatever monsters we were born to be."

As Scarlett enters her senior year at Hybrid High, she fully expects to be disappointed, but she never expected Marcus Shepherd, a jail break of dangerous Immortals, or finding her own gifts.  What started out as a typical school year, soon becomes a battle to survive to her eighteenth birthday, and, if she's lucky, graduation.
