What other book series is an amazing read?

So I picked up reading once again, I am in college and started reading really fun book series again and finished all of the Percy Jackson books after dropping it in middle school and am on Cherub: The Dealer.

I estimate I'll finish the Cherub series by the end of this month so is there any other book series out there that's action packed and sparks my imagination like these two series? I haven't read anything besides these two basically, I'm looking for action, drama, adventure, and preferably a book series, at least 2 books long. Pretty general, I know but I just love these kinds of book series, any suggestions help. Thanks in advanced!
