What to read after Night Train To Lisbon?

A huge international bestseller, with over 2 million copies sold worldwide, Night Train to Lisbon is an utterly compelling novel about one man's escape from a humdrum life in search of passion and spontaneity.
Night Train to Lisbon tells the story of mild-mannered, middle-aged Classics scholar Raimund Gregorius. When, one afternoon, he walks out of his class while in the middle of giving a lesson, his uncharacteristic impulsiveness surprises him as much as his students. This break from his usually predictable routine is driven by two chance encounters that morning on his way to work - the first with a mysterious Portuguese woman, and the second with a book discovered in a forgotten corner of an old bookshop, the journal of an enigmatic Portuguese aristocrat. With the book as his talisman, Mundus finds himself boarding the night train to Lisbon on a journey to find out more about its author, Amadeu del Prado - who was this man whose words both haunt and compel him, seeming somehow clairvoyant?
His investigations lead him all over the city, and bring him into contact with those who were entangled in Prado's life. Gradually, he makes unexpected friends and the picture of an extraordinary man emerges: a difficult, brilliant, charismatic man, a doctor and a poet, and a rebel against Salazar's dictatorship. And as Prado's story comes to light so, too, Gregorius himself begins his life anew.
Hurtling through the dark, Night Train to Lisbon is a rich tale, wonderful told, propelled both by the mystery at its heart and its evocative subject.
