I’ve just finished reading Ernest Cline’s “Armada”, it was okay but I enjoyed his first book “Ready Player One” more.
What I liked about Armada was the Links it makes to sci-fi and other films and tv of my childhood in the 70’s & 80’s. If you’re not familiar with Str Wars, Star Trek, Iron Eagle, Top Gun, Battlestar Galactica, you’ll probably not enjoy it at all.
It also leans heavily on a music playlist. Someone has created the playlist on Spotify, so if you’ve also read the book, you can listen to it here.
