Sometimes being first isn’t what you expected. Seventeen-year-old ballerina Emilia Moretti is tired of always being second best. And she’s going to prove the world she deserves to be first. In her upcoming School of the Performing Arts showcase. In the eyes of her birth parents. And in the heart of the guy she loves. She spends hours rehearsing, hours dreaming about becoming number one, hours imagining how her entire life is about to change. But when nothing goes the way she planned, she’ll need to realize what it really means to be first. Eighteen-year-old Nick Grawski doesn’t want to follow Daddy Dearest’s rules any longer. He's going to prove he's meant to be a dancer—not a lawyer—and he is not going to stay away from Em just because his father demands it. He needs to show Em that—this time around—he’s there to stay and that he won’t break her heart again. Even when her world goes down to shit, even when he finds out his dad may have been trying to protect him all along, even if being there for one another is harder than falling in love. ALWAYS SECOND BEST is a novel of hope and heartbreak and broken dreams. It’s a YA romance novel about falling in love and discovering that being first isn’t always what matters.

Number theory is one of the few areas of mathematics where problems of substantial interest can be fully described to someone with minimal mathematical background. Solving such problems sometimes requires difficult and deep methods. But this is not a universal phenomenon; many engaging problems can be successfully attacked with little more than one's mathematical bare hands. In this case one says that the problem can be solved in an elementary way. Such elementary methods and the problems to which they apply are the subject of this book. Not Always Buried Deep is designed to be read and enjoyed by those who wish to explore elementary methods in modern number theory. The heart of the book is a thorough introduction to elementary prime number theory, including Dirichlet's theorem on primes in arithmetic progressions, the Brun sieve, and the Erdos-Selberg proof of the prime number theorem. Rather than trying to present a comprehensive treatise, Pollack focuses on topics that are particularly attractive and accessible. Other topics covered include Gauss's theory of cyclotomy and its applications to rational reciprocity laws, Hilbert's solution to Waring's problem, and modern work on perfect numbers. The nature of the material means that little is required in terms of prerequisites: The reader is expected to have prior familiarity with number theory at the level of an undergraduate course and a first course in modern algebra (covering groups, rings, and fields). The exposition is complemented by over 200 exercises and 400 references.
