Nicky Gumbel's bestselling book, Questions of Life, is releasing in a US edition for the first time.

Questions of Life has sold more than 1.5 million copies since its original release by the Alpha Course founder in 1993.

The book introduces readers to the person of Jesus and helps them to discover for themselves the man that billions of people have put their trust in.

It tackles some of the big questions of life and aims to give readers a solid grasp of the basic principles of the Christian faith.

The US edition is being released by Alpha USA and features a special foreward by Alpha USA executive director Gerard Long.

"We are thrilled to have the opportunity to get this book out to the US market," said Long. "Alpha USA was not in existence when 'Questions of Life' originally hit the market in 1993 and now that three million Americans have taken the Alpha Course, we know this book will continue to help people answer some of their most daunting questions in their darkest moments."
