Eternally 21 — Linda Joffe Hull

Coupon-clipping Mrs. Frugalicious gets more than she bargained for

After Mr. Frank “Finance” Michaels loses the family's financial nest egg in a Ponzi scheme, his wife Maddie does whatever she can to help keep up the appearance that everything is financially fine. When she starts a bargain hunter's blog under the alias Mrs. Frugalicious, her website becomes a viral hit with a growing “frugarmy” of budget advice seekers.

While Maddie is researching “frugasm”-worthy deals on holiday shopping for teens, Eternally 21 store manager Laila DeSimone mistakenly accuses her of shoplifting. Then her day goes from bad to worse when Laila expires on the floor. Since Laila was a universally disliked manager, the murder suspect list is longer than Maddie's bargain spreadsheet. But when evidence points to Maddie as the prime suspect, she must track down the real culprit. Can she uncover the truth before police throw away her get-out-of-jail-free coupon for good?
