I'll admit that this was a strange one.
The early parts of the book hooked me in - our 'hero' Alma is set the task of solving an impossible murder when a body is found in the boot of a car in a fully automated car making factory. Add to this a near future setting where the majority of the population is constantly online, addicted to Shine (basically a full online existence) and you have a gripping tale to keep your brain busy.
Alma has a problem though, her partner is I'll and has to be treated every 4hrs or she will die - and only Alma can administer the treatment. This is where things nearly came unstuck for me as it seemed every 4 hours Alma would administer the treatment then get in a 'scrape' that meant she would not be able to save her partner but, thanks to epic derring-do gets back by the skin of her teeth. I nearly gave up at this point but thankfully didn't as the second half of the book really cranked things up a gear and made for a thrilling end.
The story felt both futuristic and black and white era cinema-ish with a strong Hitchcock vibe.
