Amis created very good characters. I especially liked Colonel Sun-Liang Tan who was an excellent villain as well as some of Bond's allies such as Nikos Litsas. As well as memorable characters, the novel also makes good use of location and Amis succesfully recreates Ian Fleming's style, but at the same time pushing it a little into his own areas.
It was a very promising start for the continuation series, and it is a pity that Amis didn't write any more Bonds. However, it would be a number of years until another Bond novel was published. If you are wanting to get into the continuation novels, I recommend Colonel Sun as a good starting point.
