I have Gifts on my shelf of books to read. I usually enjoy Ursula le Guin's work. I remember first coming across the Wizard of Earthsea when I was 12 - I only had about a week to read it before all the books in our temporary school library had to be sent back, and I positively devoured it. I was totally transported into the story, and then I was desperate to find The Tombs of Atuan and The Farthest Shore to finish the trilogy. The Farthest Shore scared the living daylights out of me, with all the stuff about the land of the dead.
Since then I've read a lot of her adult books, too, some of which are considered SF classics, of course. (The Dispossessed, for instance)
So do try something else, if Gifts disappointed you.
