So , I'm looking for a book that has the following things:
A male teen main character (but not too young , I would say around 14-15 years old)
and finally , a female character who has a romantic relationship with the lead , or that develops one along the story.
Something like The Inheritance Cycle , for example.
If the main character kicks ass along their adventure would be even more great.
I also love big collections , like The Inheritance Cycle , by Christopher Paolini , or The Riftwar Saga , by Raymond E. Feist.
