Well, there's 'Illuminae' by Amie Kaufman and Jay Kristoff. It's a unique blend of a story about an alien attack and told through a collection of files and records. 'The Andromeda Strain' by Michael Crichton is a classic in the alien - invasion - type story. It focuses on a deadly alien microorganism that invades Earth. Another newish one is 'Dark Matter' by Blake Crouch. While not strictly an alien invasion novel in the typical sense, it has elements of a strange, otherworldly force invading the main character's reality.
Some new alien invasion novels include 'Skyward' by Brandon Sanderson. It's not a traditional alien invasion in the sense that the 'aliens' are more of a threat from above the planet. 'Children of Time' by Adrian Tchaikovsky is also great. It involves the evolution of spiders on a planet after being influenced by an alien experiment, which in a way is a form of alien invasion of the natural order. And 'Leviathan Wakes' by James S.A. Corey, which has elements of an alien - created threat that starts to spread across the solar system.
