Holly and Georgia have been best friends since the age of 11, now they are at university together. Then they meet the clique, with enigmatic Professor Jude McDermid at their helm, and everything changes.

Holly increasingly suspects that something is wrong at Solasta Finance and with the clique. Georgia is becoming more distant and everyone is pretending that there's a perfectly reasonable explanation for everything that has happened.

Holly is ready to start her new life as part of Jude's clique. But as Georgia continues to push for a competitive position at Solasta, Holly remains suspicious - a feeling that gets even stronger when she starts to receive warning messages from a mysterious stranger. As the pressures mount on Georgia, Jude and her other girls pull tight, clinging to their old loyalties and turning a blind eye to the extraordinary circumstances around them. On an evening out, things come to a head and both new and old friendships find themselves tested to breaking point.

Holly is finally getting comfortable. Her relationship with Rory has stepped up and her friendship with the girls feels ever more real. But when an awful truth surfaces, all that is shattered.

With undeniable proof in front of her, Holly can now no longer deny the darkness of the world that she and Georgia have entered. Reaching out to Rory, she's shocked when he counsels patience in the face of such startling evidence.

Holly has been taken right to the edge, and now she's doubting every choice she's made along the way - who she's trusted to how she's acted. The stakes are sky high and there's nowhere left to turn.
