Sorry Gidde, I let that slip. Things have been a little busy.

The LHC is not at the point where it will detect gravitons - and indeed no planned collider would be able to. Gravity is very weak, very very weak. Now the chance you produce a particle in a collision is related to the strength of its coupling. The strongly coupled matter - gluons, quarks and any new strongly coupled particle like a gluino or a squark (the supersymmetric partners) - will be produced most often. Then weakly coupled matter - like W and Z bosons - will be produced less often. As the couplings decrease, the percentage of events that will produce the relevant particle decreases. There are other factors too, but the overall production rate depends on the coupling strength in all cases. The graviton coupling is so small that you will never produce enough gravitons for them to be observed.

I'm afraid I'm a terrible person to ask about popular science books. I tend to relax with good sci-fi or other fiction. I tend not to read science books outside work. I can say that Lise Randall is a lovely person - she visits NYU a lot and uses the office 2 doors down - but I've no idea what her book is like! Sorry not to be more help.
