Set in contemporary Dublin and the surrounding countryside, Ghosts and Lightning is a picaresque account of Denny Cullen's life after he is called back home to attend his mother's funeral. Denny—a sweet-natured but disillusioned young man who feels powerless in the face of death, dope, and the dole queue—is the steadiest in a cast of unstable characters. Denny and his lads fill their empty days with hooliganism, raucous parties, violence, and even an exorcism, but their fearlessness and humor make them as irresistible as an expertly pulled pint of Guinness.
