Arithmetic on Curves
Barry Mazur
Bulletin of the AMS, April 1986, pp. 207-259
Diophantine problems in number theory can usually be expressed in terms of, or related to, arithmetic questions about algebraic curves. Faltings' proof of Mordell's conjecture is a key result, which deals with important concepts of algebraic geometry, such as abelian varieties and jacobians.
The Proof of the Mordell Conjecture
Spencer Bloch
The Mathematical Intelligencer, Vol. 6, No 2, 1984, pp. 41-47
Gerd Faltings's 1983 proof of the Mordell conjecture is one of the most important accomplishments in the field of artithmetic algebraic geometry. The proof also settled, as essential steps, several other important questions as well, including conjectures of John Tate and I. R. Shafarevich.

Springer-Verlag, 2000
Modern algebraic geometry is a notoriously difficult subject. It's founded upon (and was often the motivation for) some of the most abstract concepts of abstract algebra. But the authors do a fine job, in a short book, of describing the basic principles of the subject, some of the important developments of the last 100 years, and some of the most interesting open problems. And the prerequisites are few – just a basic course in linear algebra.
