ALL OR NOTHING

by Ollie Ollerton (£16.99, Bonnier Books, HB) Ex-special Forces soldier Alex Abbott is hell-bent on avenging his brother’s death – that is, if he can stay sober long enough to hunt down the killer. A lead throws him in the path of a violent gang in the north of England, which he infiltrates by carrying out unsavoury jobs. Gaining their trust, Abbott comes closer to the depraved thrill-seekers at the organisation’s centre in this savage thriller. But can he stay ahead of his quarry?
