Reading Keep on the Borderlands appeared to be like going through a rather impersonal memoirs of "How I tamed the Borderlands", written by Eddis and Blorys, mercenaries inc.
Eddis and Blorys came from 2 different armed escort companies protecting convoys into the Keep at Borderlands. As a reward for their thwarting attempted raids, the castellan tasked them with hunting down bandits and what-nots that threatened the security of the region.
This novel is obviously not about high-level adventurers, which was fine in itself 'cos I get bored with high-level fancy stuff like Elminster casting a spell to detect all but the most powerful enemies from the safety of his lair. Eddis and Blorys had to get down and dirty, going through hostile wilderness to search out the lairs of the raiders, and wipe them out.
But the boring part was that for most of the book, they did not encounter anything that posed serious threats, and they could go on fight after fight against superior numbers.
There was a little attempt made to characterisation and PC interaction, but the basic simplicity of the plot (to rid the raiders) sort of made it rather unexciting.
What could have made the book much better was instead of finishing abruptly, an analysis of the impact of the clean-up on the Borderlands to be presented.
On the whole, fine for beginners, yawners for others.
