Ryder and Phoebe were just two siblings living in the Domain of Water. When Ryder says the words to release a curse, a beautiful girl appears the next morning. She isn't just any girl though. She is the daughter of an archangel and one of the most famous Warriors in history. When she needs to attend a trial of her past love, Ryder, Phoebe, and their friend, Blaze, escort her to the Assembly of Angels, a twelve day journey. Along the way, they have many obstacles thrown at them but will they make it in time?

"Now, I'm sure you both want to know why you are here." "Kinda," I say with a shrug. "Well, I have a job for the both of you," he begins. "There has been stuff happening in the Underworld and we need to send Warriors to investigate. Last week we sent another Warrior of Angels, Finn, to investigate and he hasn't returned or communicated with us. I want to send the both of you to the Underworld to not only investigate and find Finn but to also negotiate with Lucifer in how the Underworlders should be dealt with." "I thought it was illegal to negotiate with the devil?" I ask. "It is legal if you have permission of an archangel," he explains. "And how am I supposed to take part in this?" Augustus asks in confusion. "I am not allowed to leave the House of Angels for another month." "In exchange for you going with Phoebe, we will shorten your sentence. If this mission is successful, Augustus you will be free to do what you would like and Phoebe you will have the opportunity to choose any domain to guard."
