(Book 2) Three months after the incident that tore them apart, the four YouTubers are brought back together. Will, Lewis, Ryan and Baz haven't spoken for weeks. Recently, strange things have been happening to all of them, forcing them to remember the past. But why them? And who's behind it?

(Book 1) 5 youtubers, 5 keys to find. Sounds simple. But it's not. Rhys, Lewis, Will and the Ryans are kidnapped and locked away with no communication with anyone outside. They're only means of escape, a door covered with padlocks. Little do they know, they are being hunted down and picked off, one by one. The keys must be found before it's too late.

Lewis, more commonly known online as Dawko, travelled with his four friends - Ryan (8-BitRyan), Baz (Bazamalam), Will (of DAGames) and Razz (Razzbowski) - to Alton Towers for a three-day holiday to give them all a break from the stress of YouTube and to have a relaxing break where they could spend time together outside of work. However, sometimes it's impossible to truly get away from things. Or sometimes, a part of you just doesn't want to let go, or simply won't let you go. For stress can be a very powerful force that sometimes becomes too much to deal with; especially for one of the group's members. But one thing is for sure; this is going to be a holiday to remember.

The Insomnia Gaming Festival is a gaming convention held in Birmingham, England, and for the first time in its history, American celebrities have been invited to take part in the various stage shows. Markiplier (Mark), LordMinion777 (Wade), muyskerm (Bob), Tyler Scheid (Tyler) and CrankGamePlays (Ethan) agree to meet up with a fellow YouTuber and friend jacksepticeye (Seán) so that they can all travel to the convention together when the day comes, excited for its arrival. However, it quickly becomes apparent that things are not going to turn out how they expected, as one member of the group is struggling to contain a dark secret that only seems to be getting worse, and fears that if released it will threaten not only his life, but the lives of everyone around him. For sometimes, reality can be darker than fiction.
