Query: A cheerful and inventive early reader

There are some really fine first-chapter-book series out there. I'm thinking Daniel Pinkwater's Werewolf Club books, or Jon Scieszka's Time Warp Trio. Everything doesn't have to be fart/poop/booger or my-little-pony.These Chet Gecko mysteries are a worthy addition, although a little more advanced than very first chapter books. The stories are longer and more complicated, and the humor is a bit more sophisticated. The voice, though, is fresh and age appropriate, and the humor is broad enough to offer something to every reader.The snappy detective patter probably isn't for everyone and the actual mysteries are pretty lame, but this is certainly a good choice to try if your reader is at all adventurous. Unlike some series, the order of the books doesn't matter very much and it seems like you could start with any one of the volumes.
