Just finished "Lies" and absolutely loved it. While some characters felt a little cliche to me from say a mob or 'caper' movie, overall I thought it was really well done. If I had to nit-pick on one thing though... while I am no prude, the language was distracting to me. Same with a movie that includes the F-bomb unnecessarily every 2nd sentence. Colorful language definitely has its place, and used well can enhance the force or timbre of a statement or thought to a level perhaps not possible otherwise. However, it can also be used a crutch by anyone not able to express themselves well.
So, while I think using the actual words is worlds less annoying than making up fake ones (such as the endless use of "frak" in BSG) I think overuse can be distracting as well. I fully admit this may be due to the fact I have 3 kids 15, 12, and 9.
That said, I loved the book, and have already recommended my 15 year old read it. I think he'll like it as well.
At some point I'll definitely pick up "Red Skies" and read that as well.
