For anyone with an interest in Fatima, this is an essential read. It's not too long, and is helpfully separated into four different parts, but it's a very important book because it compiles letters written by Lucia to her bishop, the letters on which most information on Fatima is based. The first part is Lucia's initial, more brief account of the events, at which point she was still concerned about sharing the Secrets. However, the second account of events which follows is much more thorough and detailed, as at this point she was explicitly asked by the bishop to share everything. The final two parts are her memories of Jacinta and Francisco respectively, providing a real insight into what these young saints were like. The events surrounding Fatima are recounted so personally that the letters made me feel great sympathy for the little Seers who were so unfairly treated at the time; but they also inspired me to witness the great faith of the two Saints and Lucia herself.
