Thirteen Days to Midnight — Patrick Carman

You are indestructible. Three whispered words transfer an astonishing power to Jacob Fielding that changes everything. At first, Jacob is hesitant to use the power, unsure of its implications. But there's something addictive about testing the limits of fear.

Then Ophelia James, the beautiful and daring new girl in town, suggests that they use the power to do good, to save others. But with every heroic act, the power grows into the specter of a curse. How to decide who lives and who dies?

In this nail-biting novel of mystery and dark intrigue, Jacob must walk the razor thin line between right and wrong, good and evil, and life and death. And time is running out. Because the Grim Reaper doesn't disappear. . . . He catches up.
