Pursuit
Caitlyn Nicholas

Her landlord has just sold her home, all her money has disappeared along with her bigamist husband, a cyber-terrorist named Nemesis is forcing her to wreak havoc with a nasty virus, and she's developing a vile migraine.
Six years ago, Nemesis framed Dimity for the collapse of Easy Bank. The money was never found, and the bank's failure caused untold damage to its customers. She's been living under the radar ever since. The only way she can clear her name and live a normal life is to uncover Nemesis's identity, but he's always one step ahead.
Since Lord Richard Summerhayes left the Special Forces he's built the best disaster-recovery network in the world, at The Bunker in southern England. Banks, military, airports and other major systems rely on him as the last unshakeable fortress in the face of disaster. Richard has been keeping an eye on his hacker neighbour with the dubious past. He doesn't like hackers much, and when someone nukes his network with an intriguing new virus he knows exactly who to blame. But when he turns up to confront her, he gets a whole lot more than he bargained for.
When Nemesis commits an unthinkable act of terrorism, the last hope is an encrypted file that only Dimity can crack. Will Nemesis manipulate Dimity into helping him annihilate the British financial system? Or can Richard and Dimity take Nemesis down once and for all?
