I really enjoyed Thomas Sowell’s _Basic Economics_. It’s a fun read that covers a variety of economic concepts with logical analyses in a narrative format.
Also consider _Economics in One Lesson: The Shortest and Surest Way to Understand Basic Economics _ by Henry Hazlitt. It's coming from a strong Austrian school perspective, which some object to, but at a minimum by reading it you will be presented with ideas that are worth considering and debating.
