The most original AI audiobook of our time
Washington Post, Wall Street Journal, Amazon & Audible bestselling author, RR Haywood. One of the most downloaded indie authors in the UK with over four million books sold and more than 35 Kindle bestsellers.

For nearly two days, every human on Earth has been frozen by Delio’s brutal Phase One. Sunstroke, rats, and rot are setting in. In London, Alfie and his fractured team must cross a collapsing UK to reach the European kill switch. In New York, Tripal races toward Site 26A, the only other way to stop the system.

But something is wrong. Phase One hasn’t progressed, and time is running out. What was meant to save humanity now risks destroying it. As Alfie and Tripal push deeper into chaos, nothing is what it seems. And with every step, a darker question rises: is Delio still in control?

honestly I've read/listened to everything RR Haywood has written, and I'm always impressed, but sadly delio phase 2 didn't hit the mark for me.. going back and forward repeating the same dialogue is unnecessary, and towards the end I found the story to be quite rambling... what a shame because part 1 is incredible.

I don't know what went wrong here.

Like other reviews here I found this story line via the Extracted series. I can't remember how long ago I listened to Delio pt 1 so I listened to it again before starting this second installment.
I won't spoil it for anyone but I was very disappointed in the ending. I had fallen in love with a lot of the characters especially the dog. I really enjoyed the way the story looked to be going. Until I didn't.

Disappointing

So good!! Definitely worth the wait.. but now I'm questioning EVERYTHING!! Typical RR Haywood, well written, draws in you and makes you fall in love with the characters. Add in some perfect humour, a dog and a perfect twist! Well done Boss... well done!!

Oooh you bugger!

Was excited for part 2 . But found it far too choppy and was confused for most of it .
The narrator was brilliant and still enjoyed having the story back . Hopefully less chopper for the next instalment

Narration 👏

uses quite a bit of book 1 material. In the main a good book let down with deliberate off topic narratives during critical plot points which seems 'off'. Computer code is not magic, very difficult to buy into some elements of the story which relies on this idea. Not a bad book, hopefully the next one will be better.

good but with issues
