Authors with a similar style to Jonathan Stroud? (Bartimaeus Sequence, Lockwood & Co.)

I'm reading the Scarlett & Brown books for the first time right now, and he's written some standalone books I need to investigate, but I would love for some more authors with a similar flair for mixing silly humor with emotionally potent, vivid storytelling. Adult books are welcome too, not just more MG/YA! by manicbestfriend
