I have read all of Selby's books, save for "Requiem for a Dream" (though I have seen Aronofsky's superb cinema treatment of it).
All of Selby's works, up until this one, contain a savagery and hatred for the injustice and pain of this world. This world view , I think was most likely brought on by the events of his own life experiences (surgeries, amputations etc).
Selby's books are some of the most visceral, terrifying, disturbing and truthful that I have ever been fortunate to come across. Though his uncompromising lyrical savegery can sometimes be hard to take.
The fable of "The Willow Tree" is in my opinion, his best book. All of his others are black places of hopelessness, dark clammy holes with no light at all, nothing but the whispering maw of destruction and despair.
The Willow Tree brings us awareness, for the first time ever in Selby's books, of the existence of hope and forgiveness, which can be used as weapons to heal the great hurts that the world can sometimes heap upon us.
This is the book I feel truly represents the most important turning point in Selby's personal journey.
Be submerged in darkness, and through your own valor and humanity emerge cleansed.
A masterwork.
