your question is a bit vague, meaning tensor over a vector space, maybe with enough structure, are quite simple, see for example 'linear algebra via exterior products' by winitzki (this is a nice and free book, and gave me a good impression of k-vectors/forms/tensors)
the stuff gets a bit messy (as with everything) when you go to manifolds, where you have a vector space for each point and maybe you want enough structure to relate them, but then tensors behave quite well and are extensively used in diff geometry / physics(project all your memes here)
I'm not sure about a reference for the second case, maybe dodson's 'tensor geometry' (pic related, tldr its a physics book but tensors aren't)
