Seesaw Monster

Brought to you by Penguin. Some mother-in-laws are hard. This one might be murder. Miyako suspects her mother-in-law is a murderer. It’s not just a case of them rubbing each other up the wrong way – there is definitely something suspicious going on. But Miyako isn’t exactly what she seems either. Her husband has no idea about her past life as a secret agent. When she decides to use her professional skills to investigate her mother-in-law, the delicate equilibrium of their lives is thrown wildly out of balance. Many decades later, in a future world where electronic communication has been irrevocably compromised, confidential messages must be delivered by trusted couriers like Mito. But one delivery pulls Mito into a conspiracy beyond his wildest imaginings, and forces him into a race against time to defeat a world-changing technological threat. Seesaw Monster contains two sharp, thrilling linked novellas - SEESAW MONSTER and SPIN MONSTER - from the bestselling and multi-award-winning writer Kotaro Isaka, internationally celebrated for his offbeat humour and inventive talent for twists. 'Fascinating and thought provoking with some genuine surprises and incredibly clever ideas that kept me thinking about it long after I finished it… a Japanese Black Mirror !'
