Short but sweet review on Amazon:

5.0 out of 5 stars
Good series and a fun read.

I thoroughly enjoyed all three of these books, but then I also mostly agree with the philosophy put forward in them. Still, the author has great imagination and has given me what I suspect will be many hours of contemplation and fantasy. Thanks.

Of the thousand or so copies out, only 12 people reviewed it, all five stars; Amazon erased three of those reviews that came in on one day, claiming their algorithm made them do it. Sigh! So if you’ve read them and haven’t reviewed, please go here and do so — even one-line reviews help a lot to make books more visible.
