My current read: Innocent in Death by JD Robb. Publishers' Weekly says:
Once again Lt. Eve Dallas shows why she's "New York City's top murder cop" in Roberts's 24th thriller under her Robb pseudonym set half a century into the future (after 2006's Born in Death). Dallas tries to close a case at the exclusive Sarah Child Academy, where two bright 10-year-old girls discover the body of Craig Foster, a popular history teacher who proves to have been poisoned by ricin-laced cocoa. Dallas wonders if another staff member or a parent might be involved, but after the prime suspect, a promiscuous teacher who's been harassing another employee, turns up dead, the investigation takes a shocking turn. Besides a provocative puzzler, Robb provides an intense relationship update on Dallas and Roarke, her Irish power broker hubby, whose dark past--in the form of a crooked ex-girlfriend--returns to cause trouble. This prolific author, a recent Quills romance winner, is still at the top of her game.
