Stolen Blood

Sabrina Wilcox graduated from veterinary school, she took a job at a clinic that takes cares of mystical creatures. Even with the extra training needed, she loves this job.
Animals come in by themselves or they get calls and go out on them. Things take a odd turn when creatures start turning up dead. They don't know what is causing it. It doesn't take them long for them to realize that something is killing these creatures. Something is trying to meld creatures together, creating new creatures. One that they want to use against the rising magic the world has started to gather.
