The lighter side of gravity
As for 'The lighter side', well don't expect the book to be full of witty anecdotes - where it does depart from standard exposition I would call it quirky rather than amusing. For instance the last chapter looks to see whether the Steady-State theory can be salvaged. Also, although the book has been brought up to date with discussion of COBE results and the like, it does seem a bit old-fashioned - for instance there is no mention of Hawking radiation. On the other hand Narlikar does include some more general astrophysics, such as the workings of stars, which is important for getting a more solid grounding in the subject of cosmology.
