There is a timeline for Dalglish’ books. You can find it on his website. However, that does not mean you have to read the books in that order. I haven’t.
David Dalglish has created a world called Drezel. Once upon a time the brothers Ashhur and Karak came to Drezel and ended up representing dark/chaos/death and light/order/life. They are godlike-creatures who have been cast from the planet and acquired followers. Like many brothers out there Ashhur and Karak fight. Unfortunately that usually involves getting their followers to fight each other.
The Weight of Blood is a dark story, one of death and destruction. The Half-Orc brothers Harruq and Qurrah Tun are responsible for quite a bit of that destruction. These two brothers seem very different yet Harruq would do just about anything for Qurrah, even if it means killing children or friends. What Qurrah will discover in The Weight of Blood is just how far he can drive his brother. Because one thing is for sure, Qurrah manipulates his brother. In spite of this, the brothers have great love for each other.
Dalglish writes dark fantasy well. His characters are complex and loveable (in spite of their deeds). Life isn’t a matter of black and white in Dalglish’s litterary world. Instead we get shades of grey that mirror real life.
I loved his writing and the world he has created.
