1. It so needs an editor. I think the author just had random ideas about where to put the characters and stick them there with bad dialogue and confused ideas about what to do with them. There were several scenes in the book with potential but they were destroyed by confusion and dry British humor.
2. Our main character, Arthur, seems ok that earth has been destroyed. Never once do we really deal with his thoughts or feelings about what happened. All the characters for that matter are one dimensional and get annoying after several hundred pages.
3. It’s confusing. It was so hard to keep track of what was really going on as the books came and went. It just added to the sheer frustration.
I really wanted to finish the five books because I’d heard so much about this series. It was so awful. Read book one and then stop. There is no reason to continue.
