They killed Winx's sister. They slaughtered Keaton's family. Now it's time for revenge. Winx and Keaton are struggling to recover from the devastating blow dealt by the lixyns and find their way into each other's arms. The danger is only growing, a shadowy enemy lurks in the background, and Keaton's shattered heart is split between the woman from the past and the woman of his future. Now Winx has to find her revenge without losing Keaton--and without losing herself.
