Douglas does his tech research well and explains the tech very well, his books are founded on a number of interesting concepts for sci-fi fans.
But oh my word, the main characters may as well be the same in every single book.
A 30 - 40 something man, handsome, brown eyed, very clever, great sense of humor in the face of adversity, ex special forces, deeply caring, tender, possibly physically enhanced with neural implants, nanotech, exoskeleton suits.... jeeezz...
This same-in-every-book gentleman always ends up teamed with a stunningly beautiful woman 25 - 35, extremely clever, intuitive, hilarious sense of humor, deadly martial arts skills, possibly physically enhanced with neural implants, nanotech, exoskeleton suits, capable of shagging all night long.....
These boringly repetitive main characters enjoy nothing more than gooey, gushing, vomit inducing dialogue detailing how much in love with each other they are, and how much they are looking forward to having sex with each other, even whilst restrained and in the presence of their alien captors/evil baddies.
Characters (in every book) smile 'wryly' and make humorous comments 'wryly' all day long, and we are reminded on every page of the character's main attributes - intuitive, gut feeling, clairvoyant, pre-cognitive, LA detective. For fucks sake, we've been introduced to the character, we know who she is from page one!
Good near-future hi-tech scifi books Douglas, but your characters are absolutely, predictably, awful.
I daren't mention the bad guys, who once again, may as well be the same nasty bad guy in every single book.
Exciting, page turning (sometimes quite a few at a time), near future, sci-fi drivel.
