I've read many hundreds of novels (and probably thousands of short stories). Mostly in the SF&F areas, but also historical fiction and "literary" works.
Heroic Fantasy is one of my favourite genres. Unfortunately there is a lot of dross out there. I completed "Ronan's Rescue", and cannot recommend it. Derivative, contrived, poorly written. To its credit, it has a sense of fun, interesting characters and some good (but badly executed) ideas, but it just tries too hard be everything to everybody, and ends up being unfocused and shallow.
If there was any one book (or set of volumes) I could recommend, it would be Robin Hobb's "Farseer Trilogy" series. The tale of a king's b*****d trained to be an assassin in a small kingdom beset by social decay, internal dissent and treachery, and continually assailed by its enemies. Noone is truly who they appear, and the book continually peels away the layers from the characters, revealing new motives and possible choices. An utterly enjoyable read, easily in my top ten all time Fantasy novels.
