Diana explosion

She ran past him, racing toward the window wall.  She heard him shout, “Blow it!  If we can’t get the Warbringer, we can get her bodyguard.”
From somewhere she heard a tiny click, a button pressed, a fuse catching.  She vaulted over the ruins of the temple, launching herself through the window wall.  From behind her she heard an earsplitting explosion and felt a wave of heat at her back.  It thrust her forward through the air.  Her arms pinwheeled at her sides as the force of the bomb carried her too far too fast.
…
A boom sounded behind them, and Alia turned to see a cloud of flame blooming like an angry flower at the museum’s flank before the petals curled in on themselves and the explosion receded.
Diana.
…
She almost seemed to be flying, her strides long.  Alia could see that the fabric of her gown was singed, and there were welts on her skin, but she seemed whole and unharmed.
