The textbook by Nielsen and Chuang is great. If you're looking for an abridged interactive one then you might be interested in the one in the documentation for pyQuil:

It goes through the basics of quantum computing using the Forest toolkit.

Any online courses similar to Coursera?

This youtube video series is good:

Unfortunately it stops part way through the topic, still good though.
