Based off of the New York Times bestseller 'Savvy' by Ingrid Law, Fish's, Mibs's older brother's, thirteenth birthday comes to a sparkling and creative new light in gamechanger321's "Fish's Thirteenth." ~a review from: gamechanger321 ~•~ A savvy is a kind of know-how or talent that makes you special. That special know-how is especially special to us Beaumonts. Specifically on our thirteenth birthdays. Because on that day, our savvies kick into full gear. Sometimes, when you're born into a half-savvy and half-no savvy family, your thirteenth is just another birthday. Maybe a little more special than the others. But on my thirteenth birthday, my savvy kicked in alright. And, if we are talking sports, my savvy basically EXPLODED me right out uh' the park.
