Don't know much about reading lights as I'm single and don't need to worry about that. But I got a Kindle that I use when I'm away or at work.
Memory Man by Baldacci is really good, I've read all the books in that series (think it is 4 books out). Baldacci got several series that are pretty good in the crime genre.
If you want to read more good crime authors you got Michael Connelly and his series about Harry Bosch, John Connolly and his Charlie Parker-series (which delves into a bit of fantasy/supernatural stuff too), Scott Mariani (Ben Hope) and if you want something closer you have Mark Billingham and his Thorpe-series based in the London area and Ian Rankin's John Rebus up in Edinburgh.
Thank you for the suggestions. Finished Memory Man this morning, enjoyed it. I will most likely read the rest in the series.
For now I have Dan Brown The Da Vinci Code to read.
