Most of the number theory textbooks I've dealt with take a very classical approach to the subject. I'm looking for a textbook that's something like a first course in number theory for people who have a decent command of modern algebra (at the level of something like Lang's Algebra). Does such a book exist, and if it does, what is it called?


Edit: As I posted in a comment below:


In the introduction to Ireland and Rosen, they note something that was bugging me for a while, "Nevertheless it is remarkable how a modicum of group and ring theory introduces unexpected order into the subject." 


This is precisely the perspective I was looking for, so if anyone passes by this topic looking for a book that approaches number theory in this way, I feel like this quote should point him (her?) in the right direction. 



Number theory textbook with an algebraic perspective
There are probably many such books, for instance "[Fundamentals of Number Theory](http://store.doverpublications.com/0486689069.html)" by LeVeque, "[Elementary Number Theory](http://store.doverpublications.com/0486458075.html)" by Bolker and "[A Classical Introduction to Modern Number Theory](http://www.springer.com/math/numbers/book/978-0-387-97329-6)" by Ireland and Rosen.
