The Empire Trilogy is, without a doubt, one of the best fantasy trilogies you can ever find to read. I, and others i’ve met who have read it, all heartily agree on this.
Do be aware that it sits in The Riftwar Saga and — for full and complete enjoyment — you may wish to follow the reading guide i have suggested on Raymond E. Feist’s page.
