This is the final "Cupcake" installment in our series of John Green book chats. We will talk about the book and design a cupcake based on mathematical theorems! Everyone has a type, and child prodigy Colin Singleton’s type is girls named Katherine. He has dated–and been dumped by–19 Katherines. Colin is on a mission to prove a mathematical theorem he hopes will predict the future of any relationship to win the girl. Stop by the library to borrow a copy of An Abundance of Katherines by John Green today!
