Maybe you'd be interested in Zweibach's book

Looks like a pretty good place to start. I have a copy, but haven't had time to read it yet - will maybe get to it by Christmas. I've had a skim through it and it seems to proceed with only undergrad level maths (a bit of vector/tensor analysis, calculus of variations... not much more).
