2.5 stars, despite the whackadoodle ending.
Alas, said whackadoodle ending arrived too late to rescue my flagging interest. The majority was dull & predictable without any personality, while the heroine was a moron who kept missing the obvious or, when seeing it, totally misinterpreting what she saw because of no good reason other than I Hate You But Actually Love You!! hormones. (And don't get me started on her idiocy re: the hero, whom she initially loathes & despises because he was brusque with her after she accidentally stumbled into him & inanely tried to induce small talk while he was late to attend someone's deathbed, so he got annoyed & didn't stay to chit-chat for proper introductions. Seriously? SOMEONE WAS DYING. HE'S A DOCTOR. YOU WERE IN HIS WAY. Brusque manners in that scenario are not unreasonable.)
I haven't had much luck with Saucy Jack-inspired romances.** The setting is great, but I think the problems arise when heroines inexplicably decide they've solved everything & the hero is Jack the Ripper because omg, he's a doctor, he sometimes works in the slums, & he has a peen that responds to kissing me! C'mon, ladies. That's just weak. 🙄
**The exception being Seductive Caress by Carla Simpson. That one rocks. :D But IIRC, the heroine never confuses the hero with Saucy Jack -- so there you go. My theory holds true.
