The problem really with this book is it tried to do All The Things and managed to do none of them particularly well. :/ It was confused. It couldn't decide if it wanted to be one of those somewhat sappy contemporary romances with a spatula sketched on the cover, a romantic suspense, or...well, it CLAIMs it's a hot book but... seems to be a quantity vs quality issue and the only really steamy scene wasn't even with the H/h.
So the heroine is a Pollyanna type who is all smiles and cheeriness. Prior to the breakup, her ex (a chef) had her as a guest while attempting to secure himself a TV show. They were more impressed with Ms Personality than Mr Ego. The trouble with all this is that she manages to come across as a ditz. She's attracted a stalker and only gets a bodyguard at her sister's insistence. Since she only rarely seems concerned about her stalker, the bodyguard decides (after a half-assed investigation) that it's a publicity stunt.
The H is that bodyguard. He and the h had met 18 months prior while both were drowning their sorrows - him because he'd gotten involved with a celebrity client and managed to get himself fired, and her because Mr Ego dumped her. So when he arrives at her apartment and discovers who his would be client is, he tries to be all professional. He's just not very good at it. I mean really; he decides potential stalkers are safe based on interviews. No background checks, no delving into their past, nothing. Translation, he missed the creep that was right under his nose. Even better, since nobody else thought the creep was a threat (not that they had the means to investigate), the creep had access to the h's apartment, her computer, etc. And after the H has decided (based on v. little investigation really) that the h is faking it, he goes off on her, then wonders a few weeks later (after she rescued herself really) why she won't answer his emails, phone calls, etc.
Sister is shallow and self-absorbed. She blithely lets creep into the apartment, lets him see the code *and* the password on the computer. She also is the star in the only really drawn out sex scene in the book (the rest are almost quickies with dirty words thrown in to claim hotness).
The creep is a producer. Everyone assumes he's gay. Nobody actually investigates him. Guess who is decidedly hetero and has a "thing" for BDSM.
