I think I described this to a friend as an 'almost modern day London Stranger Things'... and honestly I think that sums it up quite well!

I really enjoyed the story and all the sci-fi elements were perfect. The mystery was unraveled slowly and gently in a wonderfully gripping way, but I'm torn on the ending.
It's almost too neatly tied up with a beautiful neat bow... or maybe I'm just picky!

I would recommend this for older children and early teens, as it has some sexual relationships (though no explicit scenes) and mentions of drug use (in the sense of people 'being on drugs').

I really didn't like the writing style at first. I'm not a big fan of first person or epistolary styles, however by the end I could appreciate how well it worked in favour of the story.
