I loved "The Last Day", so when I saw "The Sanctuary", I had to read it! 

The author takes us again to a dystopian place, an isolated island run by a billionaire, who supposedly created a paradise. 
Indeed he restored the population of birds that were extinct and the forest on the island is blooming... but for what cost? And what else is in the head of this man? 

Ben, who's a painter works in the city. People are killing the environment, so living on the mainland is not easy, but he's earning his money painting rich people in the Villages. The love of his life, Cara, works on the island and she supposed to come back home... until she doesn't. 

With Ben's desperation we're taken to the island, to the mystery and magic, to crazy science and impossible ideas. The vibes of the book are similar to the first one and it's just fantastic. 

I haven't read much dystopia since the pandemic started, but I had to make an exception for Andrew, who creates the world which you want to be part of, and you hate at the same time.
