Reds Robin — Riley Steel

Robin is a rather self absorbed model. On a night out, she bumps into Red, a vampire. One unholy and lustfully fantastic night later she finds herself a member of the undead. Having shied away all of her life from love, she now has to adjust to the fact that she and Red are soul mates. But something appears to be amiss with Robin, she doesn't like human blood. She is a Santorian, a special breed of vampire thought to be extinct.
As she matures she will become indestructible, impervious to sunlight. But to accomplish this she must survive on the blood of other vampires. Robin learns to love for the first time and finds her place in her new family who have welcomed her into their arms.
However, when a vicious rival vampire pack kidnaps Red, it falls solely in her hands to use her newly tuned senses to seek him out and she must battle her way through the entire vampire pack to get him back.
