The book is about the difficult road of life as a gay man. It is about the struggle in rural Ireland, the blows from a catholic mother, and the complications endured because of being different.The boy was forced to accept a promise of silence, born not out of my mother’s love to protect him, but from her selfish attitude to save her dignity from the shame of having a gay son. It was forbidden to reveal his secret, and he evolved in a home of violence and agression because he was gay. He relives his complete life from the beginning step by step. He speaks about the monstrosities that he lived, very very dark moments, the war of his life to survive, but in the end the promise of silence becomes the promise of freedom. So many wasted years of his life with the solitude of his secret, but after 17 years the promise of silence betrayed him. His parents no longer had the strenght to love him, therefore they evicted him from their lives. But the promise of silence is not only about destruction, there is also a lot of love, 13 years of love with his partner, and also love from amazing people in life that loved him for him, and how they made the difference to his existence.
