The Rise and Fall of D.O.D.O.

This is a very well written book that uses a range of writing styles (emails, journal entries, forum posts, reports etc.) to tell a hilarious, yet exciting and thought provoking tale with a bit of romance thrown in. This would have been 5 stars, but I found the ending to be abrupt and a bit of a cliffhanger, yet years after being written I can't even find a rumour of a sequel to resolve things.
