I'm a big fan of the Peter David novelisation of Batman Forever. If you haven't read it you'll be pleased to know that some enterprising person has painstakingly converted it into an ebook that you can read on any tablet or computer.
Here's the link to the page https://retroreadingtime.com/the-constant-batman/
There’s also conversions of Batman (1989) and Batman Returns as well as a host of other movie, tv and video game novelisations. I've recently become a bit obsessed about reading novelisations and this website is worth it's weight in gold.
