Terry Goodkind - Prequel - Debt of Bones (Sword of Truth)

Before the Boundaries there was the war between D'Hara and the Midlands. Zedd was First Wizard of the Midlands in charge of countering the dangerous magic of Panis Rahl, and was doing quite well until a supplicant came to the Wizard's Keep bearing a burden as heavy as bones. Abby's request was quite simple: Repay a Debt of bones by saving the people of her home, Coney Crossing, from the cluches of the D'Harans; save her daughter. But this is no simple debt to be repaid. If Zedd is to uphold his end, it might forfeit the war with D'Hara.
This is a prequel to the well-known in certain circles series "Sword of Truth" where author tells the story that happened long before Richard was born and explains why the boundaries were raised and why Darken Ral has so much hatred for Richard. It is short and won't take long time to listen or to read but might explain something.
I sincerely hope you will enjoy the book the way I did.
