Size 12 Is Not Fat by Meg Cabot (#1)
Summary: Heather Wells Rocks! Or, at least, she did. That was before she left the pop-idol life behind after she gained a dress size or two--and lost a boyfriend, a recording contract, and her life savings (when Mom took the money and ran off to Argentina). Now that the glamour and glory days of endless mall appearances are in the past, Heather's perfectly happy with her new size 12 shape (the average for the American woman!) and her new job as an assistant dorm director at one of New York's top colleges. That is, until the dead body of a female student from Heather's residence hall is discovered at the bottom of an elevator shaft.
The cops and the college president are ready to chalk the death off as an accident, the result of reckless youthful mischief. But Heather knows teenage girls . . . and girls do not elevator surf. Yet no one wants to listen--not the police, her colleagues, or the P.I. who owns the brownstone where she lives--even when more students start turning up dead in equally ordinary and subtly sinister ways. So Heather makes the decision to take on yet another new career: as spunky girl detective!
But her new job comes with few benefits, no cheering crowds, and lots of liabilities, some of them potentially fatal. And nothing ticks off a killer more than a portly ex-pop star who's sticking her nose where it doesn't belong . . .
Size 14 Is Not Fat Either by Meg Cabot (#2)
Summary: Former pop star Heather Wells has settled nicely into her new life as assistant dorm director at New York College—a career that does not require her to drape her size 12 body in embarrassingly skimpy outfits. She can even cope (sort of) with her rocker ex-boyfriend's upcoming nuptials, which the press has dubbed The Celebrity Wedding of the Decade. But she's definitely having a hard time dealing with the situation in the dormitory kitchen—where a cheerleader has lost her head on the first day of the semester. (Actually, her head is accounted for—it's her torso that's AWOL.)
Surrounded by hysterical students—with her ex-con father on her doorstep and her ex-love bombarding her with unwanted phone calls—Heather welcomes the opportunity to play detective...again. If it gets her mind off her personal problems—and teams her up again with the gorgeous P.I. who owns the brownstone where she lives—it's all good. But the murder trail is leading the average-sized amateur investigator into a shadowy world. And if she doesn't watch her step, Heather will soon be singing her swan song!
Big Boned by Meg Cabot (#3)
Summary: Life is reasonably rosy for plus-size ex-pop star turned Assistant Dormitory Director and sometime sleuth Heather Wells. Her freeloading ex-con dad is finally moving out. She still yearns for her hot landlord, Cooper Cartwright, but her relationship with "rebound beau," vigorous vegan math professor Tad Tocco, is more than satisfactory. Best of all, nobody has died lately in "Death Dorm," the aptly nicknamed student residence that Heather assistant-directs. Of course every silver lining ultimately has some black cloud attached. And when the latest murdered corpse to clutter up her jurisdiction turns out to be her exceedingly unlovable boss, Heather finds herself on the shortlist of prime suspects—along with the rabble-rousing boyfriend of her high-strung student assistant and an indecently handsome young campus minister who's been accused of taking liberties with certain girls' choir members.
With fame beckoning her back into show business (as the star of a new kids' show!) it's a really bad time to get wrapped up in another homicide. Plus Tad's been working himself up to ask her a Big Question, which Heather's not sure she has an answer for...
Size 12 and Ready to Rock by Meg Cabot (#4)
Summary: Summer break . . . and the livin' ain't easy! Just because the students at New York College have flown the coop doesn't mean assistant residence hall director Heather Wells can relax. Fischer Hall is busier than ever, filled with squealing thirteen- and fourteen-year-old girls attending the first ever Tania Trace Teen Rock Camp, hosted by pop sensation Tania Trace herself—who just happens to be newly married to Heather's ex-boyfriend, heartthrob Jordan Cartwright. But the real headache begins when the producer of a reality TV show starring Tania winds up dead . . . and it's clear that the star was the intended victim.
Grant Cartwright, head of Cartwright Records, wants to keep his daughter-in-law (and his highest-earning performer) alive. So he hires his oldest son, black sheep of the family and private investigator Cooper Cartwright—who just happens to be Heather's new fiancÉ. Heather should leave the detecting to Cooper. But with a dorm full of hysterical mini-divas-in-training, she can't help but get involved. And after Tania shares a really shocking secret with her, this reality suddenly becomes more dangerously real than anyone ever anticipated.
The Bride Wore Size 12 by Meg Cabot (#5)
Summary: Heather Wells is used to having her cake and eating it too, but this time her cake just might be cooked. Her wedding cake, that is.
With her upcoming nuptials to PI Cooper Cartwright only weeks away, Heather's already stressed. And when a pretty junior turns up dead, Heather's sure things can't get worse—until every student in the dorm where she works is a possible suspect, and Heather's long-lost mother shows up.
Heather has no time for a tearful mother and bride reunion. She has a wedding to pull off and a murder to solve. Instead of wedding bells, she might be hearing wedding bullets, but she's determined to bring the bad guys to justice if it's the last thing she does . . . and this time, it just might be.
