In this book, Lewis stimulates the senses with his descriptions of bubble trees, floating islands, colorful skies, beautiful sounds and strange creatures. (It was a compliment to Lewis when one reader complained of being seasick after reading about the floating islands.) From the standpoint of imaginative scene painting, Lewis is at his best in PERELANDRA. His plot involves a wonderful twist on an old story: the Genesis fall of mankind. It is no coincidence that Lewis was lecturing on Milton at the same time that he was composing PERELANDRA. In fact, reading Lewis's PREFACE TO PARADISE LOST, John Milton's PARADISE LOST, and Lewis's PERELANDRA in this order forms a nice trilogy, one I recommend trying. The chief shortcoming of PERELANDRA is exactly what the reader from Eureka, CA says: the story drags in the middle. The action and forward movement of the plot are too slow for my taste. Lewis's tendancy towards repetitive writing also slows things at times, especially near the very end when he goes through several pages of "praise be he" statements. Despite these pecadillos, the book is definitely worth reading for the beauty, the intriguing plot, and for background to THAT HIDEOUS STRENGTH.
