This book tells the impressive story of the young Gabriel Guilherme Estevão, dedicated from birth to the service of demons. In a clear, direct, and impressive way, Gabriel tells how he was educated and prepared to be an agent of service to the forces of darkness, and unmasks the form of performance of the fallen angels. Meanwhile, the most important - and beautiful - of this book is regarding how God reached out and freed the young Angolan, turning him into an instrument of salvation and blessing for many people. An important reading that reminds us that the great conflict between good and evil is real and that we need to choose the right and victorious side in this battle.
