Kingdom's Swords

Kingdom's Swords - David Sherman, Dan Cragg Another good entry in the Starfist series.
Lew Conorado is called back to earth to face court martial for his part in the incdent on Avionia.
Elsewhere, the Skinks that 34th FIST encountered previously start attacking a planet that is run along religious lines.

As usual, any non-Marine that is encountered is generally a self-centred, useless idiot. This book ramps that up with the various religious groups seeing the Marines a bunch of heathens (but secretly using that to hold on to their own power base by keeping the populace ill informed of anything).

Plenty of action, and a well established central group of characters makes it a good read, but the "Marines vs everyone else" approach makes it drag in places. Can be read standalone without needing to know the details from the other books but it does benefit if you have.
