I loved this series from first to last but all good things must come to an end. The authors have now got groups of characters in too many far flung locations. As they each depart for parts known, the thought comes to each that they may never meet again...sob, sob...yuck, yuck. This is getting stale. I'm also afraid that the some of the scenes in Maratha, the Sind, the coast of India, the Red Sea, Malwa, the Hind Kush, and on and on are more sound bites than plot lines.
To add interest (and pathos) to the plot, without adding new characters, the authors have decided to kill off a few folk (I won't say which ones). Two deaths were due to the chances of war...unfortunate but the series would be totally unbelievable if none or very few of the good guys died...bad guys can always drop like flies. The other death was due to causes that I do not believe were consistant with the character's development ...and that is a flaw. Finally, I'm getting the impression that someone's contribution to this volume went a little gadget crazy this time. Too many pages were spent describing the new gadget and traveling with it so it can effect large destruction of Malwa property. I appreciate that this was to some degree the raison d'etre for this series but there is such a thing as too much of a good thing.
Frankly, I did not like this book as well as the others. It's still a 4 but I hope that the series ends with the next volune. I think that the authors and these characters and this situation are running out of steam.
