The central character in this book is the planet Helliconia. The story shows how the primitive civilizations and flora and fauna are influenced by planetary forces with seasons that last thousands of years. Readers must keep in mind that this book is the start of a trilogy or they will not like the ending.
All in all it is a good start and makes me want to read the next book in the trilogy.
I really like this story of the continuing adventures of Severian. However, if you read the first book, The Shadow of the Torturer, you probably came away with a multitude of questions but don't expect to have them answered in this second book. There there are some things where you may see a glimmer of an answer and start to get an idea for what's going on, but nothing becomes absolutely clear. And as another reviewer pointed out (https://www.goodreads.com/review/show/205947975?book_show_action=true&from_review_page=1) keep a dictionary handy. I'm looking forward to reading the next book.
