The Accidental Adventures of Mr Rail: Blub (Book 1)

Mr Rail, the owner of the most well-travelled sofa in the known universe, thought he was preparing for his first day of being a teacher. He buttered the bread for his jam sandwiches and selected a tie that would suitably demonstrate his love of cats - all without realising that reality, his reality, was about to be shattered. As it turns out, this universe isn't the only one in existence.
