How to Choose
For more Wells, read The Time Machine and The Invisible Man. For invasion, try The Day of the Triffids or The Puppet Masters. For modern big ideas, read The Three-Body Problem or Contact. A simple plan is to read one classic and one modern book each month. Some older books show their age, so pay attention to the ideas as well as the style. For a book club, pair Wells with The Three-Body Problem and compare how each author imagines contact. Audiobooks make the old language easy to follow, and many are free from libraries.
