In the 18th century, on discovering her husband has been murdered, an Irish noblewoman drinks his blood and composes an extraordinary lament that reaches across centuries to the young Doireann Ni Ghriofa, whose fascination with it is later rekindled when she narrowly avoids fatal tragedy and becomes obsessed with learning everything she can about the poem. A blend of memoir, autofiction, and literary studies, 'A Ghost in the Throat' moves fluidly between past and present, quest and elegy, poetry and the people who make it.
