Between 3: Sins of a King

Book #3 in the Between series

Delas, a place where the people believed man was born to sin. The people set up a government where there was a ruler in each of the 8 desert towns. Each represents one of the 8 sins, Greed, Lust, Envy, Gluttony, Wrath, Sloth, Pride, and Agony. Each ruler had a guardian embodying a sin. Then the rulers had issued an order for their guardians, capture or kill their children. The people didn't know what they were thinking, so the people hid the children as best as they could, but two of them didn't want this. They were the twin daughters of the guardian of Greed and Agony, Jade and Ruby Valen. 4 of the children were captured with the twins attempting to save them, with the help of two strange boys.
