Wave Traveller by P.R. Morrison
After defeating "Huigor" the terrible curse, Archie Stringweed thought that he was done with exterminating curses. But when Archie hears what sounds like a marching army in the distance he suspects that something is going on.
A super curse is stirring the remains of "Huigor" causing him to feed off the energy of these combined curses. Will this curse be so powerful that it could bring "Huigor" back to full strength, heading for Archie's home town, threatening to wash it off the map!
According to I.C.E. (International Curse Exterminators), Archie is the only one who will be able to stop these curses at the exact time that they come together. What's more Uncle Rufus' life will be on the line while fighting an old curse of his own, it will be up to Archie to save him.
