All The Way Down by Eric Beetner, a crime thriller. Beeter, who in some of his other novels that I've read, has a knack of cinematic action set-pieces, only in text.
In an unnamed American city, Dale Burnett is a dirty cop who sold himself out little by little until he was a full-on lackey for crime boss Tautolu “Tat” Losopo, who has a hand in any sort of dirty business he thinks will turn a profit. Dale's slipped up, his dirty deals found out, and as he goes into a meeting with the Chief of Police, thinks he's definitely prison-bound. Instead of getting arrested though, the Chief offers him a deal. Reporter Lauren O’Brien was working on a story about Tat, and she's been kidnapped and held on the top floor of an abandoned 14-story office building that Tat has turned into his headquarters. Lauren is also the daughter of the ethically shaky, weak-willed mayor. The building has been transformed by Tat's people into a fortress. The police feel Ms. O'Brien's chances of survival are better with a one-man stealth rescue, with a dirty cop known to the gang, as opposed to a raid by an army of heavily armed SWAT team officers. And if Dale fails, well that's no great loss and there's still the SWAT option.
Getting in and freeing Lauren from Tat’s clutches proves to be cake for Dale. It’s getting out of the fortified high-rise that’s the challenge. Every story has Dale and Lauren come face-to-face with new challenges and seemingly impossible situations. Only by confronting Tat will they find freedom, and maybe in Dale's case, redemption. Meanwhile, Dale’s wife Dahlia is having a day from hell, as Tat's goons attempt to abduct her and she goes on the run, the jelly-spined mayor is being easily manipulated by his sleazy aide who has his own agenda, and various other characters get caught up in the mix, from a high-school garage band to accountants to caged slaves to heavily armed line chefs.
