Glad you didn't give too much detail. This is next to listen to in my Audible list.
I have just finished Hard Duty - Mark Cooper, good, Divergent - Veronica Roth, excellent, Dune - Frank Herbert, superb, Terms of Enlistment - Marko Kloos, excellent, the Jumper series, Enders Game series and more. Audio books are brilliant. My eyesight has been damaged by years of massive doses of narcotic pain relief and it hurts now after reading for a while, even with my new glasses, so I listen while walking, cycling, relaxing in the spa after exercise or driving on long trips. The ones that use multiple performers add an extra dimension.
Can't wait to start the Martian now
