Is there a list of available titles?
Tough to make suggestions not knowing how limited the list is.
But, coming in blind, I'm a huge fan of the Joe Ledger series.
It starts with Patient Zero
, followed by The Dragon Factory
, The King of Plagues
, and just recently the next installment was released, Assassin's Code
Probably one of my favorite series to date. Joe Ledger is just an amazing character, and his team is just as compelling.
