SENTRY #4

The world's most dangerous hero reaches his turning point: New York is overrun by a terrifying crystalline entity – and only the Sentry, back at full strength, joins forces with the Fantastic Four to keep the city from total annihilation.

Can Bob Reynolds unravel the truth behind the crystals' impossible evolution before they consume everything in their path? And will the combined might of Sentry, Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm – and even the Hulk – be enough to stop a threat that adapts to every attack?
