Fantastic Four #17 [Dnx]

DNX TIE-IN! The Fantastic Four find themselves in a strange environment, with no memory of how they got there...or worse, of who they actually are. There is a rock monster among them. They seem to have strange powers. And each of them has sustained serious injuries, including burns...burns that it's soon clear only the youngest one could've inflicted. The older man - whose limbs have a strange elasticity - has a single word written in blood on his own arm: SURVIVE. A DNX TIE-IN you won't see coming!
