I've now finished the 3rd book, Shades of Earth - it's unusual for me to read a trilogy back-to-back, but I really wanted to know how this all worked out. I think, for me, this trilogy got better as it went along, each book better than the last - I'd highly recommend it as a YA series, but it's also worth considering if you like a little science fiction, but nothing too 'heavy' or complicated.
Audio, I finished Insurgent, and I am so excited to see where the 3rd book Allegiant takes us - it'll be bought to listen to the day it comes out.
Also, my total is now at 45, which means I'm on track to at least match the last 2 years.
