This one feels too much like the author’s last few books. The formula is really showing.

This is the very definition of cheap thrills. It is fun while it lasts, but good luck trying to remember much about it later.

This one comes alive only when the author is giving information dump on ruby craftsmanship. Everything else is just okay.

For a revised version of a much older book, this one is surprisingly alright. No great, but adequately entertaining.
