Emperor of thorns
Mark Lawrence (f. 1966)
The boy who would be King has gained the throne. Prince Honorious Jorg Ancrath vowed when he was nine to avenge his slaughtered mother and brother - and punish his father for not doing so. When he was fifteen, he began to fulfill that vow. Now he is eighteen - and he must hold on by strength of arms to what he took by torture and treachery.
