The Weeping Statue by Gillian St. Kevern

Is Patrick’s faith his salvation—or his doom?
Patrick and Wiremu’s travels through Italy are not going to plan. Brain fever strikes Wiremu, forcing them to take refuge in a small Italian village. The locals are struck by Patrick’s resemblance to Sienna, a woman who died many years ago, letting them stay despite their better judgement. But as Wiremu’s condition worsens, trapping them in the village, Patrick realises their refuge is a deadly prison. Sierra’s spirit seeks revenge for her early death, killing the villagers one by one.
Urbano, the village priest, believes he has the solution to the curse hanging over the town. Patrick can save them all—if he is willing to embrace his faith once again. Patrick fears that revisiting his past will trap him once again in the cycle of fear and denial that made his life a misery, and this time, Wiremu cannot rescue him. As he sinks deeper into darkness, he realises that the only way to break this curse requires him to make an impossible choice: his love or his life.
