Thanks!

I am a fan of dark fantasy and science-fiction with abstract concepts. It is hard to pick a single favourite book, but my definite top would probably be:

• The Abyss of Hungry Eyes - Henry Lion Oldie (although I dont know whether it was ever printed in English)
• Nest of Worlds - Marek S. Huberath
• The Invincible - Stanislaw Lem
• The Tommyknockers - Stephen King
• A Song of Ice and Fire - George R .R. Martin
