This is the second book in the Agent of Evil series and it ROCKED! Loved it so much.The beginning automatically sets the tone for a darker book. After surviving months on their own they are trying to find a safe place. They issue out a radio plea offering a safe place and instead found themselves much more deeper than what they thought. I like that they plot had lots of twist and turns. The great world building of the demise around them is awesome.The characters have once again, grew so much. They learned more about each other and about the world they live in. As much as they want to save the world, they must learn how to survive in it first.They love interest progressed as I thought it would. Great friendship, stolen peaceful moments as well as self sacrifice to save one another. Totally loving and joyful to read! I'm glad that their grows stronger with each other. Their passion is uniting and lovely to read.Chaos is an exhilarating sequel. The never ending action thrusts the reader into a great thrilling read. The moment when Abby raises her gun to defend the ones she loves, the story explodes! Exciting yet strong, Chaos is amazing!
