Cloak Games book 3. Spoilers ahead. This one ties back to more of the events of the first than the second one did.
It opens with Nadia taking her brother Russell to the mall. She needs a break. And Russell's foster father notices she has stayed with them a month, rather than a night or two, since the events in book 2.
It's only an idle trip to the mall in their intention. Things go badly. It involves how Morviland wants to protect his possessions, historical novels, stealing a car, the history of the Shadowhunter she met in the first book, her resemblence to Russell, a theft she has mere hours to pull off, getting through flames, and more.
