From the NEW YORK TIMES number one bestselling author of RED QUEEN. If there's one thing Mare Barrow knows, it's that she's different. Mare's blood is red - the colour of common folk - but her Silver ability, the power to control lightning, has turned her into a weapon that the royal court wants to control. Pursued by the vengeful Silver king, Mare sets out to find and recruit other Red-and-Silver fighters to join the rebellion. But Mare finds herself on a deadly path, at risk of becoming exactly the kind of monster she is trying to defeat. Will she shatter under the weight of the lives that are the cost of rebellion? Or have treachery and betrayal hardened her forever?
