Love this series! With each book, the story becomes more complex and involved, building the back story of the invasion a bit at a time. Hell Squad makes more of a guest appearance here and the story revolves around Roth, head of squad 9 (LOVE the idea of an all female squad with a couple of token men) and Avery, a new character, briefly mentioned in a previous book.
Written with Ms. Hackett’s wonderful style and talent, ROTH is a definite hit and must read in this genre. Great narration by Jeffrey Kafer & Samantha Cook who bring the action and the characters to life
