This book was comprised of 6 novellas; Queen Song which is a prequel to the series from the perspective of Cal's mother; Steel Scars is another prequel from the perspective if Farley leading up to the events that take place in the 1st book (Red Queen); World Behind is in the perspective of 2 new characters and takes place during the events of the 4th book (War Storm); Iron Heart is in the perspective of Evangeline and takes place after the events of War Storm; Fire Light is in the perspective of Cal & Mare and takes place after the events of War Storm; Fare Well is in the perspective of Maven and takes place during the events of War Storm.

All in all I was not impressed. I was kind of excited to read about other events in different POVs, but everything was just meh.
