She's a misfit with no present. He's a bad boy with no future. And they have 23 days to save the world. A deadly plague divided humanity into three different species. An ongoing ecological crisis has plunged the world into chaos. What's left of the once-powerful United States in 2081 is a scorched wasteland where day-to-day survival is a struggle. Life in the pristine bubble of the Greater Los Angeles District isn't as idyllic as the Central Protectorate wants its citizen to believe. Iris Flores and her friends are relegated to the edge of a society that has no use for them—until the day she is hunted down and forced to leave her home to spy on the enemy. The wayward son of Cascadian political royalty, Xander Kendrick is once again in trouble after pummeling a man in front of dozens of witnesses. When given the choice to serve his sentence in the Army instead of going to a maximum-security prison, he accepts the former. Little does he know that the military stint will set him on a collision course with danger... and Iris. As loss and betrayal destroy their lives, Iris and Xander will risk everything to save the people they love.

The Domino Trilogy comes to a thrilling conclusion! Execution? Check. Murder? Check. Betrayal? Double check. Xander and Iris have seen it all. Hey, when it rains, it pours.

Alone in a strange land and hiding from the Central Protectorate while a war is raging back home, he fights a battle of his own to save Iris. If those odds weren’t bad enough, they must somehow find a way to return to Cascadia and stop an army from annihilating the country. Their world and everyone they love are doomed if they fail.
