Books on higher dimensional elementary differential geometry

Question

I am looking for information on hypersurfaces embedded $\mathbb{R}^n (n>3)$, mostly on their curvature and second fundamental form. Most books I have looked at only contain information on surfaces in $\mathbb{R}^3$ and then jump straight to abstract surfaces (generall manifolds) where everything is too abstract for me. I'd like to learn how to state/describe the curvature of a hypersurface in the most elementary way possible. Are there any (somewhat) modern books that give a nice reference on this topic? Thanks in advance.
