In addition to the mentioned Cornell--Silverman book there is another Cornell--Silverman (+Stevens) collection named "Modular forms and Fermat's last theorem" (http://www.springer.com/mathematics/numbers/book/978-0-387-98998-3), which I can warmly recommend. It's available in paperback.

The purpose of the volume is to cover the material used in the proof of Fermat's last theorem. Therefore a lot of arithmetic geometry is covered at a reasonable graduate-level (maybe a few more demanding surveys, though). Brian Conrad from previous comments is responsible for one nice paper in the volume.

I especially like Tate's paper on Finite group schemes and Mazur's on deformation theory of Galois representations.
