The Undeclared War takes place in the post-pandemic world of 2024 against the backdrop of an upcoming British general election involving the UK's first Black Conservative prime minister. It tracks a leading team of analysts at the heart of the UK's NSA-style spy agency GCHQ as they attempt to ward off a cyber-attack on the country's electoral system.

Saara Parvan is a young student doing work experience in the GCHQ Malware Department, while other characters include Kathy Freeman, an American cyber-analyst on attachment at GCHQ from the NSA, and GCHQ head David Neal.
