(WARNING: This book contains spoilers of the 2016 turtle movie. Don't read the description if you don't want to be spoiled.) Griz, a young shapeshifter faces her first battle to save the city she loves with the four turtle brothers that live the city as well. With Shredder now out of prison, Griz and her turtle family, known as her brothers, meet some new allies and get all the help they can to defeat Krang who wants to destroy planet earth. With the help of two mutants, Bebop and Rocksteady. Griz then comes in contact with purple ooze that makes her have seconds thoughts on becoming human and fitting in with the city above. Donnie is then told to not say anything about the ooze, leaving the brothers and Griz in conflict. Will Krang be defeated with the humans not accepting the turtles and Griz?
