The Martian – Brilliant. If you haven’t read this one, its probably #1 on this list.
Field of Prey (The Prey Series Book 24) – This was a pretty terrific Prey book. I hadn’t read this series in a while and a friend recommended it. I tore through it. The last 25% of the book is very intense. If you’re interested in trying this series, start from the beginning: Rules of Prey. You won’t be disappointed.
