YA recommendation to cleanse after some serious reads

Every year, I throw in a YA book series to cleanse after reading some books on more serious matters. I just finished reading Dennis Lehane’s Small Mercies, Shutter Island and Mystic River and now am looking for a “fun” throwaway read. For example, I have enjoyed the Red Rising books, the Scythe series, The Reckoners series, The Maze Runner, Enders Game and The Inheritance Cycle. Anyone have any recommendations for a fun YA read that a 30 y/o dude can enjoy?
