Twelve-year-old Blake was worried that summer break in Fever Swamp would be b-o-r-i-n-g, but it's quickly become more intense than she ever could have imagined. After a close encounter with some werewolves in the swamp, Blake is separated from her new friend Lily and all alone. But a stunning discovery will make her wonder just who Lily really is... and who the real monsters are! The wild werewolf nightmare continues in this all-ages scarefest from New York Times bestselling author Marieke Nijkamp (This Is Where It Ends, Before I Let Go, The Oracle Code) and artist Yasmin Flores Montanez (Marvel Action: Captain Marvel, Tilly).
