YOU HAVE TO READ THE UNDERLAND CHRONICLES!!!! They are just amazing. They have adventure, great characters, great plot, and that tiny bit of romance that makes it great. From the word 'Gregor' in the first book to the word 'name' in the last, you will be absolutely hooked. BEWARE The books say 'hell' and 'hellish' a couple times, there is bad attitudes, and at least one or more gory death in each book, but it is just the best fantasy series ever!
