In this epic conclusion to the New York Times bestselling Infinity Cycle trilogy, two brothers find themselves in a heartbreaking war against one another . . . 

After the ultimate betrayal, Emil must rise up as a leader to stop his brother, Brighton, before he becomes too powerful. Even if that means pushing away Ness and Wyatt as they compete for his heart so he can focus on the war.

 Brighton has a legion of followers at his command, but when he learns about an ancient scythe that can kill the unkillable, he realises that’s all he needs to become unstoppable against Emil and other rising threats.      Meanwhile, Maribelle aligns with her greatest enemy to resurrect her lost love, and Ness infiltrates political circles to stop Iron from ruling the country, but both missions lead to tragedies that will change everyone’s lives for ever. As the Infinity Son and the Infinity Reaper go to war, who will be crowned the Infinity King?
