Having discovered Planking by the bais of "silence of the Warriors," I admit I was surprised by this author agréblement. The trilogy has the merit to combine many themes dear to science fiction. Not about hard science or scientific credibility to the imagination! In a vivid imagination who will introduce us to the most incredible worlds cultures and surprising as each other. The last book "The Hyponéros citadel" is my strongest taste for enjoying a masterful final and anthological. Halfway between the space-opera fantasy and fantasy!
