4 stars.
#2 in the series.
Reread (many years later) so I can read them in order. Since I didn't remember much of the book it was fun. It also helped fit characters in the time line of the series together. Since I'm a fan of all things Library of Alexandria, I can imagine I may read this one yet again in the future.
Since I wasn't feeling well, the three days it took to read felt longer.
I particularly like the Writer's Note and Interview at the end of the book.
I'm looking forward to rereading (and reading for the first time) the rest of the series, in order.
