Blood Calling — Joshua Grover-David Patterson

Lucy Leary's eighteen year old life is a wreck. Her parents divorced, she's earned a DUI, and her grandfather has died. He left her a single possession: A vampire slaying kit with a note that says, "They're real. Fight them." Lucy finds answers in a place she never expected--the homeless shelter where she has to perform her community service. The Sundown Shelter is only open at night, and the man who runs it disappears during the day. But digging into the truth is dangerous. What Lucy learns will force her to abandon her life and confront an ancient vampire out to get her family.
