I think this is the best InterLynk novel yet. Agent Boone had has become a nicely rounded character, with flaws and strengths, both of which play into this classic spy thriller. If James Bond and Black Widow were to have a baby, it would be Doctor Hildebrant Boone, slick, kick-butt, ruthless, flawed and vulnerable.
Like all of Dale Amidei's novels, the protagonist goes through a crisis of faith after the loss of her lover in the prior novel, but it's handled subtly in the form of Lin, a Chinese dissident Christian who Boone is assigned to smuggle out of the People's Republic of China and keep alive long enough to be offered asylum. In addition to new enemies, an old enemy crops up as well, now a hired gun, to prevent that from happening. No moustache-twirling villains here, you can feel Yameen's hatred, his motivation, his bloodlust and his greed. The plot twist with the hackers is absolutely brilliant. You'll never feel the same way about your banking transactions again.
This book has a hilarious episode at the end which I won't spoil, but let's just say, don't mess with Boone, and don't mess with her friends!
