Chubby Is The Night (Nexus Chronicles, #3.5)

Max just wanted to have a night out with her cousin and go home. As a plus sized lass she didn't fit in amongst the tiny blonde gazelles, but protecting her cousin from a perv in the alley changed her fate. In a moment of self preservation when a man started chewing on her neck, she bit the hand over her mouth, setting a paranormal chemical reaction into play. Now that she is infected with his blood, he either needs to turn her or destroy her. The vampire tribunal chips in with an option for Max. She can rescue their kidnapped Guild Master, and he will decide her fate. Sounds like the best deal of the evening.
