Trope-y and slightly sexist, but a duo worth rooting for, with a complicated action plot-thread
Bess is a strong heroine, and only once rather foolish-risk-taking (i.e., without a good reason). Wade is a good guy, if too prone to making "protective" decisions without consulting the one he's trying to protect, such as by keeping facts from them. (We learn he did it to his single mother, too ... but he does respect Bess enough that he's working on doing better now.)
Obviously, the relationship is predicated on the very trope-y idea that their one night together, where they each knew the other was using a false name, nevertheless changed both of them, and meant enough that they haven't even really wanted to be with anyone else in the meantime. In that, Bess has been managing better than Wade, because (a) she's had her baby to look out for, and (b) he knew he *could* have found her, if he'd ever decided that she wouldn't actually be better off without him. Frankly, in the first scene, I'd say his boss ought to have fired him, or at least demoted him to second string, for lousy work ethic, given that the job makes complete situational awareness vital.
The team are pretty likable, with typical banter and support, and I'm glad the author seems to be taking their client choices in a more firmly "good guys" direction, so they can continue together (Bess now included), and Wade's battered conscience will be okay. The female "best hacker" they have to hire from outside for assistance will clearly be joining them, and she's fun, though she does have a misandrist(sp?) chip on her shoulder, seeing insult even at times it was not intended.
Don't read this book if some bad language (f--- in its various forms, and likewise s---, maybe others I've forgotten) will offend you, or the fact that every one of the protagonists is fine with the idea of her stalker ex being better off dead, as long as it can be done without landing in jail.
The action/ suspense elements become tangled by the fact that they're not sure whether one or two groups are involved in the attacks on the safehouse, and whether Bess, little Parker, a previous client (due to the antagonists possibly having bad intel), and/or the team themselves are being targeted.
My only as-yet-unmentioned criticism of the plot is that Bess is unwilling to consider that any of it might involve coincidence. I'll grant that coincidence is a device that obviously occurs a lot more often in bad fiction, but to believe that it's an illusion 100% of the time is equally foolish. Looking for explanations when there really aren't any is what makes ridiculous conspiracy theories develop.
Finally, as for proofreading and editing, I didn't catch any internal inconsistencies, just a handful of minor typos: AFAICR, there are a couple missing or wrong short words, a couple stray apostrophes in plurals, and a couple should-be apostrophes that are actually single opening quotes. Some of that's probably the fault of AutoCorrupt.
Will I read more of this "popcorn" series? Hmm, a definite maybe, especially if they stay in KU.
