Gangpire (Gangpire Trilogy, Volume 1‪)‬

Life has never been a walk in the park for Tacoma. With a crack addict as a mother, and no father, he has been responsible to take care of his little sister Seattle since he was nine, while living in one of East Oakland's most notorious drug and gang infested neighborhoods. Every day is a struggle; they're forced to steal food, and have to rely on their street wits to survive. Lucky for them, Tacoma's best friend Raider's grandmother, Mama Marcella, shields them from getting detected by Social Services. Tragedy strikes one fateful day when Tacoma asks Raider to pick Seattle up from school. But Raider forgets, and Seattle never makes it home. Tacoma's world shatters around him, and he vows to wreak violent revenge on those responsible for her disappearance. But they are only teenage boys, and no match to fight Seattle's powerful abductors. Raider has an idea. With the help of an ancient Santeria book he stole from his grandmother, he turns both of them into vampires. Their bloody journey to save Seattle takes them deep into the corrupt underworld of the Oakland police force, secret FBI task forces, a beautiful scientist, and death. As the two unleash their newly acquired powers, things get quickly out of control. Tacoma and Raider turn their friends into vampires to help them fight against powerful enemies, and together they leave a trail of dead bodies along the entire West Coast. Follow Tacoma on his desperate quest to find his sister, while spiraling deep into the world of an escalating vampire war…
