The Truth Of The Matter by Andrew Klavan.
Read my review of The Last Thing I Remember.
Read my review of The Long way Home.
Roamnce:A couple kisses, falling in love/remembering falling in love.
Violence:People shooting at you, getting shot, dangerous (like you could die)situations, some fighting scenes and a good guy/ bad guy chase scene that ended in a car wreck.Charlie has memory attacks that are painful.
What I thought:Better than the last two(they were awesome too, but this one took the cake :) .It was tying things in so well!And such a big shock when his last contact is revealed.It was very well written.
Rating & Age:5 stars. 13/14 up.
