In Wumbers, language converges with math to create something new and surprising (and seemingly cryptic at first glance). Avery did a double-take the first time she read it. Jumping between the linguistic and and mathematical, mid-word, keeps readers nimble and on their proverbial toes. The hybrid text promotes a type of mental dexterity, flexibility and a different kind of fluency. The linguist in me is smitten with wordplay books like these. Just s2pendous.
