Monster roar

Hey!’ Annabeth yelled.
The monster let the woman go.Both sets of eyes fixed on Annabeth as if thinking, Do you have a death wish ?
Then it threw back its heads and roared in harmony. The sound hit Annabeth like an ice pick between the eyes. The windows of the train shattered. Mortals who had passed out were startled back to consciousness. Some managed to crawl out of the doors. Others tumbled through broken windows.
Through blurred vision, Annabeth saw the monster crouched on its mismatched forearms, ready to pounce.
