Hmmm this was my first Barclay book and I'm a bit on the fence about it. I love first person, read a TON of first person (Including Lisa Gardner who excels at 1st person) so I'm VERY picky about my first person. For about the first 1/3 to 1/2 the first person is very clunky and awkward :( but I stuck with it. The last half or so was better (less clunky, better pacing)--mostly because (I think) there was more dialogue than anything.
Odd as my criticisms may sounds, I feel like I had a vested interst in seeing how it all turned out so I stuck with it. Keeping in mind that suspense and thrillers are my #1 genre of choice to read (meaning, I've read a lot and I'm really picky, as in, "Can you pass the Gardner test?" LOL)...There were no huge surprises here. And in the end, I'm not 100% sure I bought into all the big reveals that went on. I def wouldn't read any of Barclays older books but MIGHT maybe give a newer book a try to see if the writing/plotting/etc has improved.
