What to expect

Third-grader Aven Green has been solving mysteries for a really long time—a whole month!

She has solved many important cases like The Mystery of the Cranky Mom, The Mystery of the Missing Ice Cream, and The Mystery of the Smelly Feet. Her record is nearly 100 percent, with only The Mystery of the Cereal in My Underpants remaining unsolved to this day.

Aven asks all the right questions, wields her detective kit carefully, and follows up on every clue. Then her teacher’s lunch bag, with her lunch still in it, is taken, and Aven’s great-grandma’s beloved dog goes missing. Can this perceptive detective crack two cases at the same time?

Luckily, Aven has a superpowered brain full of lots of extra brain cells to take on both cases. See, she was born without arms, so all of the cells that were supposed to make her arms went into making her brain instead. At least that’s her working theory for The Mystery of Why I Have So Many Extra Brain Cells.

Critics Review

  • “For Aven, having no arms hasn’t stopped her from living life to the absolute max! Young readers will laugh aloud at Aven’s funny reactions to queries about what happened to her arms…[and] will be intrigued by the practical skills she has perfected…A recommended purchase.”

    School Library Journal (starred review)
  • “Unapologetically smart and refreshingly confident in her abilities, this super-sleuth extraordinaire is a joy to tag along with.”

  • “Peppered with humorous malapropisms and leaps of kid logic…a showcase for Aven’s precocious personality…witty, stubborn, and self-confident.”

    Kirkus Reviews
  • “Bowling centers earnest Aven’s quirky wit, determination, and earnestness, introducing an exuberant adoptee whose disability does not exist to serve the plot.”
