I love to read series. Books I can immerse myself in for fairly long periods, with characters and/or ongoing story lines that evolve over volumes. I like science fiction. (Not fantasy.) My favorite all-time is Asimov, particularly the Foundation/Robots series). But I also like crime drama, suspense, thrillers. I will consider almost any series at all, even history, if it's really interesting.
Anyway, I'm looking for recommendations. I'm in-between right now and haven't found anything lately that lights the fire in me. I need your help.
