Archfiends Basilisk and Worm are about to hijack Hero HQ. First, though, they've got to infiltrate HERO.COM, the website from which heroes download their abilities.
When the site crashes, for some reason Pete, Toby, Lorn and Emily are the only ones left with powers... and they're not exactly brilliant at the job at the best of times.
But with the world under threat, there is nobody else. It's up to the friends to out-think, out-pace and out-plot the evil masterminds.
