Dash and the Euclidean Worm Queen (en Inglés) - Seth Daugherty;Adam Maguire

What if everything you thought you knew was wrong? In Dash & the Fibonacci Fungus, Dash and Rudy used their mathematical methods to solve the mystery of a strange illness that befell the citizens of Euclid, Indiana. At least, that's what they thought. Turns out, they fingered the wrong culprit, and the actual culprit is back. It's a manhunt this time (sort of), and Dash and Rudy hope to be up to the task. Meanwhile, Dash, Rudy, and Chief are all navigating new ventures, taking them out of their comfort zones and threatening to distract them. The stakes are high, and time is of the essence. Will they succeed? Find out in this second installment, Dash & the Euclidean Worm Queen.

Once again, a copy of Dash's Math Notes is included in the back of the book for anyone who wants to learn more about the concepts employed by our young mathematicians.
