Unlike a lot of Coursera courses, the course is a series of interactive (mostly text) pages and some multiple-choice questions. In something like this, where sometimes you can breeze through, and sometimes you need to take a few minutes, I really like that.
Raymond Smullyan has a bunch of puzzle books that are easily approachable, and some more formal books.
George Polya has a book called "How to Solve It."
There's a great graphic novel "Logicomix" that can give a good introduction to people involved in analytic philosophy.
Thinking in Bets, Annie Duke
How to Decide, Annie Duke
Asking the right question: A guide to critical thinking, Browne & Keeley
Thinking in Systems, Meadows
My computer science education included CS philosophy where a.o. this was a course text.

In fact any intro to discrete math, real analysis, abstract algebra, number theory,..., or combinatorics book would work.
Another choice would be the book, 'The Trivium: The Liberal Arts of Logic, Grammar, and Rhetoric : Understanding the Nature and Function of Language' by Sister Miriam Joseph.
I attended the course - and learned a lot!

Highly recommended. Also provides good preparation if you want to go on to study topics like non-standard logic and automated proof systems.
