recommended reading list 

  • The House of the Dead – Fyodor Dostoevsky
    Based on Dostoevsky's own imprisonment in a Siberian labour camp, this powerful novel explores suffering, freedom, resilience, and the complexity of human nature. Through vivid portraits of fellow prisoners, it asks what remains of humanity when everything else is stripped away.

  • All Men Are Mortal – Simone de Beauvoir
    What if you could never die? De Beauvoir follows an immortal man whose endless life gradually drains the world of meaning. A profound existential novel examining mortality, purpose, ambition, and whether our limited time is what gives life its value.

  • The Man Who Mistook His Wife for a Hat – Oliver Sacks
    A fascinating collection of real neurological case studies that reveal how the brain shapes perception, identity, and reality. Sacks combines science with compassion, showing that behind every neurological disorder is a deeply human story.

  • The Fall – Albert Camus
    Told as a confessional monologue, The Fall follows a once-successful lawyer who slowly exposes his own hypocrisy and moral failures. Camus explores guilt, judgment, self-deception, and the uncomfortable truths we often hide from ourselves.

  • East of Eden – John Steinbeck
    A sweeping family saga inspired by the biblical story of Cain and Abel, exploring love, jealousy, free will, and redemption across generations. At its heart is the enduring question of whether we are bound by our nature or free to choose who we become.

  • The Woman in White – Wilkie Collins
    One of the first great mystery novels, this Victorian classic blends suspense, romance, and psychological intrigue. Filled with hidden identities, conspiracy, and unforgettable characters, it keeps readers questioning whom they can trust until the very end.
