David Dalglish: A Dance of Mirrors

Hi everyone

A Dance of Mirrors is the third and final book in the Shadowdance series by David Dalglish. 
I read this on my e-reader. 

"Haern is the King's Watcher, protector against thieves and nobles who would fill the night with blood. Yet hundreds of miles away, an assassin known as the Wraith has begun slaughtering those in power, leaving the symbol of the Watcher in mockery. 
When Haern travels south to confront this copycat, he finds a city ruled by the corrupt, the greedy and the dangerous. Rioters fill the streets and the threat of war hangs over everything. To forge peace, Haern must confront the deadly Wraith, a killer who would shape the kingdom's future with the blade of his sword. 
Man or God; what happens when the lines are blurred?"

I did not enjoy this. I find Haern to be so, so stupid in his decisions and actions. He had me rolling my eyes countless times. How can he not see what his actions will bring? 
There's no depth to the characters, and contrary to what I had hoped, this doesn't get better further in the series. 
It's easy to read and a lot happens but then again, there's no real point to it all. It doesn't go anywhere.

I'm not sure I'll try anything else by Dalglish and if I do, what I should read. Do you have a suggestions?

Happy reading!
