Original Sin: Hulk vs. Iron Man

If, like me, you enjoy Tony Stark and Bruce Banner having feelings about science and ethics at each other, you will enjoy this book immensely. If you're actually looking for a Hulk vs Iron Man fight, I mean... that's in here too. But it's mostly feelings.

also this is the first and maybe only book I've read from the Original Sin event, but if you're willing to accept that Tony and Bruce have swapped memories for ~space reasons~ it reads fine on its own.
