In 1957, newly-qualified nurse Lily Gaynor set sail for Guinea-Bissau to live among the Papel tribe. Tuberculosis, malaria and typhoid were rife. Children were grossly malnourished; witchdoctors flourished. Lily set up a clinic under the mango trees administering penicillin — ‘God’s Needle’.

Filled with one arresting story after another, God’s Needle tells of Lily’s faithfulness in the face of considerable opposition as she provided medical care, preached the gospel and translated the Bible. And from these humble beginnings God has grown the church in Guinea-Bissau to be one of the largest in West Africa.
