A fall-through-the-rabbit-hole-into-an-alternate-world story. Specifically, falling through a grate behind the dryer in a laundry room and landing in an underground city populated by humans who cohabit the same space with giant-sized cockroaches, bats and rats -- of of which talk, by the way. The 'warrior' from up top (aka: Overland) has to go on a quest and fulfill a prophecy. This has a much simpler plot than Narnia and is targeted for younger readers (lower middle school, at least by my estimation), but I've got a thing about other-worldly-type stories and now that I've started on this 5-book series, I'll read my way through it.
