"Dead Run"
Death of Christina Alexandrova.
*What's happened to the Speed Force? One of the world's most powerful speedsters is dead, and Barry Allen must discover who – or what – is responsible! But the reborn Barry is a man haunted by a dark secret in his past. A secret that drives him to push far beyond his limits. A burden that, if he's not careful, could send him right back into oblivion! Geoff Johns and Ethan Van Sciver's reinvention of the Scarlet Speedster picks up the pace – we dare you to keep up!
